Here is how to loop through two lists at the same time in Python.

first_list = [1, 2, 3]
second_list = [10, 20, 30] 

for i, j in zip(first_list, second_list):
    print(i, j) 

Copy & Run

1 10
2 20
3 30

We need to use the Python zip() function to stack the lists together. The zip function extract pairs of items from the two lists and create a list of tuples. Each tuple will have a pair of items.
