How to loop through multiple lists using Python?
The most straightforward way seems to use an external iterator to keep track. Note that this answer considers that you're looping on same sized lists.
example
a = [10, 12, 14, 16, 18] b = [10, 8, 6, 4, 2] for i in range(len(a)): print(a[i] + b[i])
Output
This will give the output −
20 20 20 20 20
Example
You can also use the zip method that stops when the shorter of a or b stops.
a = [10, 12, 14, 16, 18] b = [10, 8, 6] for (A, B) in zip(a, b): print(A + B)
Output
This will give the output −
20 20 20
