Python List Reverse

Reverse List Using Slicing

Slicing with the negative step, we get items in reverse format.

Example

colors_list = ["Red", "Blue", "Green", "Orange"]
print(colors_list[::-1])

['Orange', 'Green', 'Blue', 'Red']

In the output, you can see that slicing with the negative step reverses all items.

Reverse List Using Reverse Function

A list of items can reverse using Python's inbuilt reverse() function.

Example

colors_list = ["Red", "Blue", "Green", "Orange"]

colors_list.reverse()

print(colors_list)

['Orange', 'Green', 'Blue', 'Red']

This output shows that all the list items reverse using the reverse() function.

Reverse List Manually

To reverse all items using logic, you must iterate the original list, pick items from the end and add them to the new temporary list.

Example

colors_list = ["Red", "Blue", "Green", "Orange"]
new_colors_list = []

length = len(colors_list)
temp = length - 1

for i in range(length):
    new_colors_list.append(colors_list[temp])
    temp = temp - 1

print(new_colors_list)

['Orange', 'Green', 'Blue', 'Red']

In the output, you can see that all the list items reverse manually, using for loop iteration.
