    TXT File reading

    Hi, i'm relatively new to python programming and have been asked to do a project for university. I'm attempting to make a user account program with a register, login and lost password function.

    I've decided to go down the route of when a user register their account, the vars to temporarily store the username, email & pw are then added to a dictionary. The dictionaries at the end of the registration then are saved to a external txt file.

    I have reached my first problem in that I don't know how to read from the text files and create an if statement to check whether an email exists for example.

    The code so far:

    option = True
    register = True

    userdict = {}
    pwddict = {}
    emaildict = {}

    f = open('db.txt', 'a')

    while (option):
    print("""Choose from one of the following options...
    1) Register
    2) Login
    3) Lost Password""")
    option = input("")
    if option == '1' or option == 'register':
    print("You have chosen to register")
    option = False
    elif option == '2' or option == 'login':
    print("You have chosen to login")
    option = False
    elif option == '3' or option == 'lost password':
    print("You have chosen the lost password function")
    option = False

    print("We will need a username, your email and a password.")
    username = input(str("Type your desired username: "))
    email = input(str("Type your email address: "))
    password = input(str("Type your password: "))

    emaildict [username] = email
    pwddict [username] = password
    print("Your details have been saved, you will receive email confirming containing your details shortly.")
    Any help is appreciated!

    I'm sure your question is interesting and important.

    You should use the pickle or shelve module. These are documented here. python 2

    or python3 here
    [code]Code tags[/code] are essential for python code and Makefiles!
