How does nested for loop work, 2,3,4

Answer 1

for x in list1:
for y in list2:
print(str(x) +str(y)

Answer 2

Nested for loop means, that inside an 'outer' for loop, an 'inner' for loop is running. Sample:

l1 = ['a','b','c']
l2 = [1, 2, 3]

for outer in l1: # outer loop
for inner in l2: # inner loop
print(f'{outer}{inner}', end= ', ')

# output: a1, a2, a3, b1, b2, b3, c1, c2, c3,

As you can see the first outer value is taken, and then a complete iteration on the inner loop is done. Then next outer value and again a complete iteration on inner loop is done, and so on...
