Python: Swap two sublists in a given list

Python List: Exercise - 186 with Solution

Write a Python program to swap two sublists in a given list.

Sample Solution:

Python Code:

nums = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
print("Original list:")
print(nums)
nums[6:10], nums[1:3] = nums[1:3], nums[6:10]
print("\nSwap two sublists of the said list:")
print(nums)
nums[1:3], nums[4:6] = nums[4:6], nums[1:3]
print("\nSwap two sublists of the said list:")
print(nums)

Sample Output:

Original list:
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]

Swap two sublists of the said list:
[0, 6, 7, 8, 9, 3, 4, 5, 1, 2, 10, 11, 12, 13, 14, 15]

Swap two sublists of the said list:
[0, 9, 3, 8, 6, 7, 4, 5, 1, 2, 10, 11, 12, 13, 14, 15]

Python: Tips of the Day

Decapitalizes the first letter of a string:

Example:

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:

pythonTips
