Python string doesn't support reverse function so we must use a slice that steps backward. That is extra the slice statement [::-1]. In fact, In Python, strings are ordered sequences of character data.
Generally, There is no built-in function to reverse a String in Python.
Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform related Python strings queries.
In this context, we shall look into a complete guide on how to reverse a string in Python.
We have a string "Hello World" and we will reverse it by executing the following command:
str ="Hello World" [::-1]
The output will look like this:
What does this imply ?
We must use the slice statement [::-1] because it will start at the end of the string until the beginning of the string. -1 means one step backward.
The slice statement [::-1] will directly impact the str variable, so that the above string will be reversed.
Let's try writing your own command and extra the slice statement [::-1].
How to Create a function ?
If you want to send your strings into a function and return them backward:
return x [::-1]
myback = string("Hello World")
The output will take the following look:
What does this mean ?
The slice statement [::-1]
Call the function and replace variable x with a string
