Python: Shuffle the elements of a given list

Python module: Exercise-6 with Solution

Write a Python program to shuffle the elements of a given list.

Use random.shuffle()

Sample Solution:

Python Code:

import random 
nums = [1, 2, 3, 4, 5]
print("Original list:")
print(nums)
random.shuffle(nums)
print("Shuffle list:")
print(nums)
words = ['red', 'black', 'green', 'blue']
print("\nOriginal list:")
print(words)
random.shuffle(words)
print("Shuffle list:")
print(words)

Sample Output:

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

Original list:
['red', 'black', 'green', 'blue']
Shuffle list:
['green', 'blue', 'black', 'red']

Python: Tips of the Day

Inverts a dictionary with non-unique hashable values:

Example:

def tips_collect_dictionary(obj):
  inv_obj = {}
  for key, value in obj.items():
    inv_obj.setdefault(value, list()).append(key)
  return inv_obj
ages = {
  "Owen": 25,
  "Jhon": 25,
  "Pepe": 15,
}
print(tips_collect_dictionary(ages))

Output:

{25: ['Owen', 'Jhon'], 15: ['Pepe']}
