Reverse String or List

Reverse a String or List in Python

Python makes it very easy to reverse a string or list using slicing or built-in functions.

Python Program

text = "Python"
print(text[::-1])           # nohtyP

nums = [1, 2, 3, 4, 5]
print(nums[::-1])           # [5, 4, 3, 2, 1]
print(list(reversed(nums))) # [5, 4, 3, 2, 1]

# Reverse without slicing
rev = ""
for ch in text:
    rev = ch + rev
print(rev)                  # nohtyP

Expected Output

How it Works

• [::-1] slicing is the shortest way to reverse.
• reversed() also works; or build a reversed string in a loop.

Summary

• Python makes it very easy to reverse a string or list using slicing or built-in functions.
