Python: Interleave multiple lists of the same length

Python List: Exercise - 126 with Solution

Write a Python program to interleave multiple lists of the same length.

Sample Solution:

Python Code:

def interleave_multiple_lists(list1,list2,list3):
    result = [el for pair in zip(list1, list2, list3) for el in pair]
    return result
     
list1 = [1,2,3,4,5,6,7]
list2 = [10,20,30,40,50,60,70]
list3 = [100,200,300,400,500,600,700]
print("Original list:")
print("list1:",list1)
print("list2:",list2)
print("list3:",list3)
print("\nInterleave multiple lists:")
print(interleave_multiple_lists(list1,list2,list3))

Sample Output:

Original list:
list1: [1, 2, 3, 4, 5, 6, 7]
list2: [10, 20, 30, 40, 50, 60, 70]
list3: [100, 200, 300, 400, 500, 600, 700]

Interleave multiple lists:
[1, 10, 100, 2, 20, 200, 3, 30, 300, 4, 40, 400, 5, 50, 500, 6, 60, 600, 7, 70, 700]

Python: Tips of the Day

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
