Python: Reverse a given list of lists

Python List: Exercise - 150 with Solution

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

Sample Solution:

Python Code:

def reverse_list_of_lists(list1):
    return list1[::-1]
colors = [['orange', 'red'], ['green', 'blue'], ['white', 'black', 'pink']]
print("Original list:")
print(colors)
print("\nReverse said list of lists:")
print(reverse_list_of_lists(colors))
nums = [[1,2,3,4], [0,2,4,5], [2,3,4,2,4]]
print("\nOriginal list:")
print(nums)
print("\nReverse said list of lists:")
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]]

def tips_decapitalize(s, upper_rest=False):
  return s[:1].lower() + (s[1:].upper() if upper_rest else s[1:])
print(tips_decapitalize('PythonTips'))
print(tips_decapitalize('PythonTips', True)) 

Output:
