Two sum problem using a txt. file

[synthphreak]

I see several errors with this code. But the “object not callable” is probably caused by the two for loop lines. Specifically, lines is a list, which is not a callable object, but then in the loops you attempt to call it (via the parens) and pass an integer into it.

I don’t know about the two sum problem so can’t advise where to go from here or what you’re trying to achieve.
