HELP! I've been working on this assignment for a while and can't get it to work. It's supposed to pull contact info from a text file, and then return it. Every time I try to run it , it returns "no entry found" no matter what.
HELP!

Before print('No entry found') you could add print(name) and print(firstname) to see why the if name in firstname returned false.

You don't increment "count" correctly in the file input (I would guess since we don't know the layout of the file). The printing of lastname, firstname, etc. should show that. Also, use one lookup function only. Past the list to use to the function. So to lookup lastname, pass the lastname list to the function and "last name". Then input "Enter the %s to look up" % lit_passed_to_func.
