[answerhappygod]

Answer needs to be in Linux. I am reading a username and
password from text file userlist.txt.
userlist.txt has about 20 usernames and passwords.
the format of all the text is username:password in a long
list . Can you tell me why this code is not reading in the
username and password??
also the code crashes after I enter in the zipcode
Thanks!
