Learn how to reverse a String in Python.

There is no built-in function to reverse a String in Python.

The fastest (and easiest?) way is to use a slice that steps backwards, -1.

Example

Reverse the string "Hello World":

txt = "Hello World"[::-1]print(txt)

We have a string, "Hello World", which we want to reverse:

The String to Reverse

txt = "Hello World"[::-1]print(txt)

Create a slice that starts at the end of the string, and moves backwards.

In this particular example, the slice statement [::-1] means start at the end of the string and end at position 0, move with the step -1, negative one, which means one step backwards.

Slice the String

txt = "Hello World"[::-1]print(txt)

Now we have a string txt that reads "Hello World" backwards.
