How to Reverse a String in Python

In Python, like most programming languages, strings are just a sequence of characters.

Unfortunately, there is no built-in function to reverse a string in Python. However, there are still a few ways to reverse a string in Python.

In this post, we'll take a look at the different ways to reverse a string in Python.

Reverse a String using Slicing

The most straight-forward way to reverse a string in Python is to use the slicing operator.

The slicing operator is denoted by a colon (:) and it allows you to access a range of elements in a sequence.

We can use the slicing operator to reverse a string by specifying the start and end indices of the string.

Let's take a look at an example:

PYTHON
string = "Hello World"
reversed_string = string[::-1]

print(reversed_string)

The output of the above code is:

BASH
dlroW olleH

This works because we are specifying the start and end indices of the string and the step size is -1. This means that we are starting from the end of the string and moving backwards by 1 character at a time.

Reverse a String using reversed

Alternatively, we can use the reversed function to reverse a string in Python.

The reversed function takes a sequence as an argument and returns a reversed iterator.

We can then convert the reversed iterator to a string using the join function.

Here's an example:

PYTHON
string = "Hello World"
reversed_string = "".join(reversed(string))

print(reversed_string)
