如何在python中使用raw_input将元组作为输入？

Question

I am trying to take input. But it's not the correct syntax.

a, b, c = (int(x) for x in raw_input().strip(' '))

My idea is to take multiple values from single line which has integers separated by space. How can I do it?

Answer 1

You were very close. It's split not strip :

a, b, c = (int(x) for x in raw_input().split())

This will take exactly 3 integers, no more no less. If you want to take an arbitrary amount into a tuple, try this instead:

tup = tuple(int(x) for x in raw_input().split())

Answer 2

I'm guessing you want the split function, not the strip function. That will return an array that you can iterate over. The strip function will just remove initial and trailing characters (in your case spaces).

That will throw an exception if the user doesn't enter data in the correct format though.
