# lists to save in a tuple

 P: n/a 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 Jun 27 '08 #1
