2 Ways to Reverse a List in Python 3

This concise article shows you 2 ways to reverse a given list in Python 3. The first approach is to use slice notation and the second one is to use the reversed() function. Without any further ado, let’s see some code.

Using slice notation

Example:

list1 = [1, 2, 3, 4, 5]
list2 = ['A', 'B', 'C']

list1_reversed = list1[::-1]
list2_reversed = list2[::-1]

print(list1_reversed)
print(list2_reversed)

Output:

[5, 4, 3, 2, 1]
['C', 'B', 'A']

Using the reversed() function

Example:

list1 = [1, 2, 3, 4, 5]
list2 = ['A', 'B', 'C']

list1_reversed = list(reversed(list1))
list2_reversed = list(reversed(list2))

print(list1_reversed)
print(list2_reversed)

Output:

[5, 4, 3, 2, 1]
['C', 'B', 'A']
