how to iterate over 2 lists at same time?

Question

here is a example what i want

x = [1,2,3]
y = [1,4,9]

for i in x:

for j in y

these two for loops should run combined but how?

Answer 1

for i, j in zip(x, y):
# your code

Answer 2

lol even easier.

for i in range(len(x)):
# your code

What is the issue?

Bhavik Mahalle if the iterables have the same length, you can just get length of one of them. Then do whatever to both iterables in the loop cause they use the same indexes

Answer 3

Bhavik Mahalle ,

the best way is to use zip, but it can also be done with for loop:
(enumerate() is used to get additionally an index, which is used in the loop body to access the values)

x = [1,2,3]
y = [1,4,9]

for ind, _ in enumerate(x):
print(f"{x[ind]} - {y[ind]}")

# result:
1 - 1
2 - 4
3 - 9

Answer 4

for i in x:
for j in y:
# your code
