Hello,

I have two lists and would save them in a tuple.

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

with the next statement I can do that:

t = [(x,y), for x in a for y in b]

This gives the next list:

[(1,'a'),(1,'b'),(1,'c'), (2,'a'),(2,'b'),(2,'c'), (3,'a'),(3,'b'),
(3,'c')]

But I want the next list:

[(1,'a'),(2,'b'),(3,'c')]

Would somebody tell me how I can solve this problem?

Regards,
Nader
