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

Last update on December 21 2024 07:34:09 (UTC/GMT +8 hours)

Write a Python program to interleave two lists into another list randomly. Use the map() function.

Sample Solution:

Python Code:

# Import the 'random' module
import random

# Define a function named 'randomly_interleave' that takes two lists as input
def randomly_interleave(nums1, nums2):
    # Create a list of iterators using the 'iter' function for each input list
    iterators = [iter(nums1)] * len(nums1) + [iter(nums2)] * len(nums2)
    # Use the 'random.sample' function to randomly select iterators from the list and create a new list of values
    # Use the 'map' function with 'next' to extract the values from the selected iterators
    result = list(map(next, random.sample(iterators, len(nums1) + len(nums2))))
    # Return the result
    return result

# Define two lists 'nums1' and 'nums2'
nums1 = [1, 2, 7, 8, 3, 7]
nums2 = [4, 3, 8, 9, 4, 3, 8, 9]

# Print the original lists
print("Original lists:")
print(nums1)
print(nums2)

# Print a newline for better readability
print("\n")

# Print a message indicating the operation to be performed
print("Interleave two given lists into another list randomly:")

# Print the result of calling the 'randomly_interleave' function with the 'nums1' and 'nums2' lists
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]
