using two variables in for loop?

Question

How can we use two variables simultaneously in for loop?

for x, y in data1, data2:
print(x, y)

Answer 1

You must do nested loop, or eventually if both structures are list with same number of items ( or dict sharing same properties ^^ ), with a loop on the shared indexes ( or keys )...

Provide much of your code case context if you want more accurate answer ;)

Answer 2

for x in data1:
for y in data2:
print(x,y)

or if their lengths are same

for i in range(0,len(data1)):
print(data1[i],data2[i])
