Login and register code

[Ameldan5]

I have to make code that lets you create an account or log in and it must save the accounts to a text file, I have done the create account but its very badly done and don't have a clue how to do the login as I don't understand read files, thank you for any help




(Login code I wrote)

def reg():
    uname=input("Please a username: ")
    pword=input("Please a a passwrd: ")
    f = open("UNPW.txt", "a")
    f.write("\nUsername:"+uname)
    f.write("\nPasswod:"+pword)
    f.write("\n----------------------------")
