Python: Interleave multiple lists of the same length. Use itertools module
Python Itertools: Exercise-29 with Solution
Write a Python program to interleave multiple lists of the same length. Use the itertools module.
Sample Solution:
Python Code:
import itertools
def interleave_multiple_lists(list1,list2,list3):
result = list(itertools.chain(*zip(list1, list2, list3)))
return result
list1 = [100,200,300,400,500,600,700]
list2 = [10,20,30,40,50,60,70]
list3 = [1,2,3,4,5,6,7]
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: [100, 200, 300, 400, 500, 600, 700] list2: [10, 20, 30, 40, 50, 60, 70] list3: [1, 2, 3, 4, 5, 6, 7] Interleave multiple lists: [100, 10, 1, 200, 20, 2, 300, 30, 3, 400, 40, 4, 500, 50, 5, 600, 60, 6, 700, 70, 7]

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']}
