Python: Interleave two given list into another list randomly using map function

Python map: Exercise-14 with Solution

Write a Python program to interleave two given list into another list randomly using map() function.

Sample Solution:

Python Code:

import random
def randomly_interleave(nums1, nums2):
    result =  list(map(next, random.sample([iter(nums1)]*len(nums1) + [iter(nums2)]*len(nums2), len(nums1)+len(nums2))))
    return result
nums1 = [1,2,7,8,3,7]
nums2 = [4,3,8,9,4,3,8,9]
print("Original lists:") 
print(nums1)
print(nums2)
print("\nInterleave two given list into another list randomly:")
print(randomly_interleave(nums1, nums2))

Sample Output:

Original lists:
[1, 2, 7, 8, 3, 7]
[4, 3, 8, 9, 4, 3, 8, 9]

Interleave two given list into another list randomly:
[4, 3, 8, 9, 1, 2, 4, 3, 7, 8, 3, 7, 8, 9]

Example:

# How to merge two dictionaries
# in Python 3.5+

x = {'p': 1, 'q': 3}
y = {'q': 5, 'r': 8}

z = {**x, **y}

z
{'r': 4, 'p': 1, 'q': 3}

z = dict(x, **y)
print(z)

Output:

{'p': 1, 'q': 5, 'r': 8}
