Python If Else Statement - Explained with Examples

This article covers how to use the if else statement in Python. In fact, An if else Python statement evaluates whether an expression is true or false. If a condition is true, the "if" statement executes. Otherwise, the "else" statement executes. Python if else statements help coders control the flow of their programs.


Python Conditions and If statements

Python supports the usual logical conditions from mathematics:

  • Equals: a == b
  • Not Equals: a != b
  • Less than: a < b
  • Less than or equal to: a <= b
  • Greater than: a > b
  • Greater than or equal to: a >= b


Python Nested if statements

We can have a if...elif...else statement inside another if...elif...else statement. This is called nesting in computer programming.

Any number of these statements can be nested inside one another. Indentation is the only way to figure out the level of nesting. They can get confusing, so they must be avoided unless necessary.


Python Nested if Example

'''In this program, we input a number

check if the number is positive or

negative or zero and display

an appropriate message

This time we use nested if statement'''


num = float(input("Enter a number: "))
if num >= 0:
    if num == 0:
        print("Zero")
    else:
        print("Positive number")
else:
    print("Negative number")

Output 1 will give:

Enter a number: 5
Positive number


Output 2 will give:

Enter a number: -1
Negative number


Output 3 will give:

Enter a number: 0
Zero

Abstract Factory – Design Patterns in Python

This article covers Abstract Factory design pattern in Python.

Basically, The Abstract Factory design pattern can also be used to create cross-platform UIs without coupling the client code to concrete UI classes and keeping all created views consistent with different operating systems.

Abstract Factory is a creational design pattern, which solves the problem of creating entire product families without specifying their concrete classes.

Abstract Factory Method is a Creational Design pattern that allows you to produce the families of related objects without specifying their concrete classes.
Using the abstract factory method, we have the easiest ways to produce a similar type of many objects.
It provides a way to encapsulate a group of individual factories.

Advantages of using Abstract Factory method:
This pattern is particularly useful when the client doesn’t know exactly what type to create.
1. It is easy to introduce the new variants of the products without breaking the existing client code.
2. Products which we are getting from factory are surely compatible with each other.

Disadvantages of using Abstract Factory method:
1. Our simple code may become complicated due to the existence of lot of classes.
2. We end up with huge number of small fies i.e, cluttering of files.

Examples of Factory pattern in Python:
1. With the Factory pattern, you produce instances of implementations (Apple, Banana, Cherry, etc.) of a particular interface -- say, IFruit.
2. With the Abstract Factory pattern, you provide a way for anyone to provide their own factory. This allows your warehouse to be either an IFruitFactory or an IJuiceFactory, without requiring your warehouse to know anything about fruits or juices.

Unit Testing in Python - A Quick Overview ?

This article covers the concept of Unit Testing in Python. Testing in Python is a huge topic and can come with a lot of complexity, but it doesn't need to be hard. You can get started creating simple tests for your application in a few easy steps and then build on it from there.

Here, You'll learn about the tools available to write and execute tests, check your application's performance, and even look for security issues.


pytest supports execution of unittest test cases. The real advantage of pytest comes by writing pytest test cases. pytest test cases are a series of functions in a Python file starting with the name test_.


pytest has some other great features:

1. Support for the built-in assert statement instead of using special self.assert*() methods

2. Support for filtering for test cases

3. Ability to rerun from the last failing test

4. An ecosystem of hundreds of plugins to extend the functionality


Running Your Tests From Visual Studio Code

If you're using the Microsoft Visual Studio Code IDE, support for unittest, nose, and pytest execution is built into the Python plugin.

If you have the Python plugin installed, you can set up the configuration of your tests by opening the Command Palette with Ctrl+Shift+P and typing "Python test". 


How to Use unittest and Flask

Flask requires that the app be imported and then set in test mode. You can instantiate a test client and use the test client to make requests to any routes in your application.

All of the test client instantiation is done in the setUp method of your test case. In the following example, my_app is the name of the application. Don’t worry if you don’t know what setUp does. You’ll learn about that in the More Advanced Testing Scenarios section.


The code within your test file should look like this:

import my_app
import unittest

class MyTestCase(unittest.TestCase):
    def setUp(self):
        my_app.app.testing = True
        self.app = my_app.app.test_client()
    def test_home(self):
        result = self.app.get('/')
        # Make your assertions

You can then execute the test cases using the python -m unittest discover command.

An Introduction to Python Async IO

This article covers an Overview of Async IO in Python. Python 3's asyncio module provides fundamental tools for implementing asynchronous I/O in Python. It was introduced in Python 3.4, and with each subsequent minor release, the module has evolved significantly.

Asyncio is the standard library package with Python that aims to help you write asynchronous code by giving you an easy way to write, execute, and structure your coroutines. 

The Asyncio library is for concurrency, which is not to be confused with parallelism.


Concurrency does not mean Parallelism and vice-versa.

We can combine them both. 

We can have multiple threads, running Tasks parallely but each thread may not be running Tasks concurrently. 


Note:

1. Asynchronous IO (async IO): a language-agnostic paradigm (model) that has implementations across a host of programming languages.

2. async/await: two new Python keywords that are used to define coroutines.

3. asyncio: the Python package that provides a foundation and API for running and managing coroutines.

Notch Up Producer-Consumer Paradigm with Python

This article covers how producer-Consumer pattern is a very useful design which can be leveraged to a varied extent in order to enable asynchronous processing of multiple time-consuming tasks. The concept has been widely incorporated in modern-day messaging queues viz. Kafka, RabbitMQ, Cloud MQs provided by AWS, GCP, and so on.

Python provide Queue class which implements queue data structure. We can put an item inside the queue and we can get an item from the queue. By default this works in FIFO (First In First Out) manner.


The function producer will put an item inside queue and function consumer will get an item from the queue. We will use following method of queue class by instantiating queue object q = Queue().


Queue Method Python:

q.put(): To put an item inside queue.

q.get(): To get an item which is present inside queue.

q.join(): This method stops python program from exiting till it gets signal from the below method task_done. Hence this method should always be used in conjunction with method task_done

q.task_done(): This method should be called when item got outside from the queue using q.get() has been completely processed by consumer. When all items make call to their respective task_done it sends signals to q.join() that all items have been processed and program can exit.


Threads class Python:

Python allows writing multi-threaded program using Thread class. We will instantiate object of thread class and make use of following methods to process (consume) multiple items concurrently:

t = Thread(target=consumer): Instantiate thread object which would make call to function consumer.

t.start(): Starts execution of thread by making call to function consumer.

Asynchronous Programming in Python - More about this ?

This article covers how to make applications performant and efficiently use CPU cycles and threads. However, it is not all rainbows and unicorns when talking about asynchronous code.

Asynchronous programming is a type of parallel programming in which a unit of work is allowed to run separately from the primary application thread. When the work is complete, it notifies the main thread about completion or failure of the worker thread. 

There are numerous benefits to using it, such as improved application performance and enhanced responsiveness.

On the other hand, A synchronous program is executed one step at a time. Even with conditional branching, loops and function calls, you can still think about the code in terms of taking one execution step at a time. When each step is complete, the program moves on to the next one.


Examples of synchronous program:

1. Batch processing programs are often created as synchronous programs. You get some input, process it, and create some output. Steps follow one after the other until the program reaches the desired output. The program only needs to pay attention to the steps and their order.

2. Command-line programs are small, quick processes that run in a terminal. These scripts are used to create something, transform one thing into something else, generate a report, or perhaps list out some data. This can be expressed as a series of program steps that are executed sequentially until the program is done.

Install and Run Python on CentOS 8 - How to do it ?

This article covers how to install python2 and python3 on CentOS 8. By default, python2 and python3 are not installed on CentOS 8. To install both, you need to install all python packages separately according to python versions. Also, you can run python2 and python3 environments on your system. 

The 'alternatives --auto python' command is used to set any python version as the default. 


To run Python in Linux:

A widely used way to run Python code is through an interactive session. 

To start a Python interactive session, just open a command-line or terminal and then type in python, or python3 depending on your Python installation, and then hit Enter .


Python comes preinstalled on most Linux distributions, and is available as a package on all others. 

However there are certain features you might want to use that are not available on your distro's package. 

You can easily compile the latest version of Python from source.


Installing Python 3 on Linux:

1. To see which version of Python 3 you have installed, open a command prompt and run

$ python3 --version

2. If you are using Ubuntu 16.10 or newer, then you can easily install Python 3.6 with the following commands:

$ sudo apt-get update

$ sudo apt-get install python3.6

3. If you're using another version of Ubuntu (e.g. the latest LTS release) or you want to use a more current Python, we recommend using the deadsnakes PPA to install Python 3.8:

$ sudo apt-get install software-properties-common

$ sudo add-apt-repository ppa:deadsnakes/ppa

$ sudo apt-get update

$ sudo apt-get install python3.8

4. If you are using other Linux distribution, chances are you already have Python 3 pre-installed as well. If not, use your distribution's package manager. For example on Fedora, you would use dnf:

$ sudo dnf install python3


To see if pip is installed, open a command prompt and run:

$ command -v pip

WordPress error "Could Not Save Password Reset Key To Database" - Fix it Now ?

This article covers methods to resolve WordPress error "Could Not Save Password Reset Key To Database" which usually occurs when we try to login into our WordPress site.

As the database is part of the hosting space, you'll get that database error when you fill-up the entire available disk space of your account.
That can happen if you created several staging sites or uploaded too many large files like big images on your website.

A more common reason for this WordPress issue can be substantial backup files created by your backup plugin.

Backup files need a lot of space on your system, which can quickly fill up the entire available webspace.
1. So to fix this WordPress error, immediately log in to your website using an FTP client like the Filezilla program or the File Manager in your cPanel hosting dashboard.
2. Then go to the media folder wp-content/uploads and check there for large files which you can delete, for instance, backup files with the ending .*zip or large media files with the file extension *.tiff, *.png, or *.png.
3. You should never use the *.tiff format, though. This one uses a lot of disk space, so it's better to use *.jpg instead of that.
4. After, open your WordPress website, log in, or use the password reset function again.

To fix this WordPress error in cPanel:

1. You'll need to free up space on your server.
2. Log into the HostPapa Dashboard and click My cPanel.
3. Then select Files > cPanel File Manager.
4. Navigate to your WordPress root folder and select wp-content/uploads.
5. Search through your upload files to locate and delete large files that you may no longer need.

This article covers methods to fix 'Are you sure you want to do this' error in WordPress for our customers.

One of the most common solutions is to revert your website to an older backup before the error occurred. If you update your backup regularly, it is one of the most powerful tools to use against errors.

The process includes disabling your themes and plugins while checking to see if the error is fixed. If you have a lot of plugins, this process may take a while. Deactivating the plugins will not be enough because they can still cause a problem. This is why it is recommended to uninstall a plugin if you are not using it.
2. Log into the cPanel and click on the File Manager. Click on the public-html directory and locate the wp-content folder. This folder contains all of the content on your website. Locate the plugins folder and right-click it.

Googlebot cannot access CSS and JS files – Resolve crawl errors ?

This guide covers website crawl errors, Googlebot cannot access CSS and JS files. Google bot and other search spiders will visit the robots.txt file of your website immediately after they hit the htaccess file.

Htaccess has rules to block ip addresses, redirect URLs, enable gzip compression, etc. The robots.txt will have a set of rules for the search engines too. 

They are the reason you received "Googlebot Cannot Access CSS and JS files". 

Robots.txt has few lines that will either block or allow crawling of files and directories. Google has started penalizing websites that block the crawling of js and css files.

The JavaScript and cascading style sheets are responsible for rendering your website and they handle forms, fire events, and so on.

If the JS is blocked, Google bot will not be able to crawl the code and it will consider the code as a spam or violation of link schemes. 

The same logic applies for the CSS files.


To resolve "Googlebot Cannot Access CSS And JS Files" Warning:

1. You need to remove following line: Disallow: /wp-includes/

Depending upon how you have configured your robots.txt file, it will fix most of the warnings. 

You will most likely see that your site has disallowed access to some WordPress directories like this:

User-agent: *

Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/plugins/
Disallow: /wp-content/themes/

2. You can override this in robots.txt by allowing access to blocked folders:

User-agent: *
Allow: /wp-includes/js/

This package is included in various WordPress plugins and themes.

You can fix this issue by trying to Remove the example.html file located in the genericons directory.


The recommended way to patch your system is simply to upgrade WordPress. 

This will not only secure your system against this vulnerability, but also any other issues that may have been fixed.

To do so, log into your WordPress server and navigate to your document root directory.

You can remove the offending files by typing:

sudo find . -path "*/genericons/example.html" -exec rm -f {} \;

You can then check your directory structure again:

find . -path "*/genericons/example.html"

 All of the example.html instances within a genericons directory should be removed.


#Genericons includes a file called example.html which has been found to be vulnerable to attack from the Document Object Model level. 

Any WordPress plugin or theme that includes this file is open to an attack. 


To help combat this, we have done the following for VaultPress users:

1. We've deleted the file everywhere we can to proactively secure your site.

2. We've added it to our security scanner so that if there are any cases where we couldn't detect the file or couldn't delete it, you will still be notified if the file exists on your site. 

3. For users with sites where we couldn’t remove the file, we have personally emailed each of you with steps to remove the file and details about where the file is located.


Also, another important security update was released today for #WordPress in Version 4.2.2. Version 4.2.2 fixes several vulnerabilities that could allow users to compromise your site including the Genericons vulnerability.

WordPress Not Sending Email error

If you're experiencing issues with WordPress failing to send emails – for example, sending forms or other communications – it's usually due to problems with your server configuration. 

If your WordPress email is not being sent, switch over to SMTP (Simple Mail Transfer Protocol) instead.

WordPress has several SMTP plugins you can use to force any FROM address you like.

This is important for two major reasons: 

i. It allows you to send email directly through your mail server as opposed to the web server. 

ii. It allows you to send email FROM another email host.

One major reason why this happens is that webhost disable the PHP Mail function because it is very easy to exploit by spammers and hackers.

When WordPress wants to send emails, it calls on the email server in your webhost using the PHP Mail function, but if this function is disabled by your webhost, your requests to send emails will not even get to your mail server.

WordPress fails to send email as a result of the SMTP server on the underlying operating system not being configured properly. 

Proper configuration includes using authentication, configuring the basic SMTP server settings, and following best practices when setting up SPF records, and so on.

This article will guide you on the method to fix WordPress not sending email issue.
