Getting Username and Password from a file(Python)

I'm trying to write a program that allows me to get a username and password from a file. I feel like I am on the right track but, when I run the program to test whether or not it works, I get a:

Name error: global name Username is not defined.

Any ideas where I've gone wrong? I apologize if the formatting is off.

    def login():
        UserName = input("Please enter your user name: ")
        passw = input("Please enter your password: ")
        check(UserName, passw)
        return UserName, passw

    def check(user, password):
        pword = {}
        for line in open('unames_passwords.txt','r'):
            user, password = line.split()
            pword[user] = password
            if user == UserName and password == passw:
               return True
               print("Thank you for logging in.")
            else:
               print("Username or password is incorrect")

    def main():
        login()

    main()

Your check function doesn't have any variable named UserName.
Instead, it has a parameter named user, which is then overridden by the line from the file.

You need to change the parameter to a unique name, then use that name.
