Python: Reverse a given list of lists

Python List: Exercise - 150 with Solution

Reverse List of Lists

Write a Python program to reverse a given list of lists.

Sample Solution:

Python Code:

# Define a function called reverse_list_of_lists that takes a single argument 'list1'.
def reverse_list_of_lists(list1):
    # Use slicing to reverse the order of the elements in the 'list1'.
    return list1[::-1]

# Create a list 'colors' containing sublists.
colors = [['orange', 'red'], ['green', 'blue'], ['white', 'black', 'pink']]

# Print the original list.
print("Original list:")
print(colors)

# Print a message indicating that the list of lists is being reversed.
print("\nReverse said list of lists:")

# Call the 'reverse_list_of_lists' function to reverse the 'colors' list and print the result.
print(reverse_list_of_lists(colors))

# Create a list 'nums' containing sublists with different lengths.
nums = [[1, 2, 3, 4], [0, 2, 4, 5], [2, 3, 4, 2, 4]]

# Print a message indicating that the original list is being displayed.
print("\nOriginal list:")
print(nums)

# Print a message indicating that the list of lists is being reversed.
print("\nReverse said list of lists:")

# Call the 'reverse_list_of_lists' function to reverse the 'nums' list and print the result.
print(reverse_list_of_lists(nums))

Sample Output:

Original list:
[['orange', 'red'], ['green', 'blue'], ['white', 'black', 'pink']]

Reverse said list of lists:
[['white', 'black', 'pink'], ['green', 'blue'], ['orange', 'red']]

Original list:
[[1, 2, 3, 4], [0, 2, 4, 5], [2, 3, 4, 2, 4]]

Reverse said list of lists:
[[2, 3, 4, 2, 4], [0, 2, 4, 5], [1, 2, 3, 4]]

Flowchart:

Flowchart: Reverse a given list of lists.

Python Code Editor:
