##  Noels Music Game - A Solution by Colin
##  needs a two column .csv file with artist and song name
##  needs a hst.txt file with 5 rows of 0,n/a added (to "prime it").
##  feel free to tinker
## uncomment line 98 for testing

import random  ## added for what reason

## manually add new items here, username and password ## what other approach could you do
user_list = ["colin", "clive", "pragya"]
password_list = ["fire","wind","sky"]

# setting a flag to false so loop below runs at least once
access_ok = False

#  answers for first run
user_name = input("enter user_name or Q to Quit: ")
user_pword = input("enter password: ")

#
while access_ok != True:
    # check for Q to quit
    if user_name =="Q" or user_name == "q":  ## is there another way of doing this?
        exit()  ## not pretty but stops the prog, is there a cleaner way maybe

    elif user_name in user_list:  # checking if the user_name is in the user_list list
        # if it is, then get the index of the user_name pull back the password from password_list and check if matches password entered
        if user_pword == password_list[user_list.index(user_name)]:
            print ("Access Approved, welcome " + user_name)
            access_ok = True # change the flag so while loop no longer runs

        else:  # bad password entered
            print("invalid Password, try again")
            print(f"you entered <{user_name}> for the username and <{user_pword}> for password")
            user_name = input("enter user_name or Q to quit: ")
            user_pword = input("enter password: ")

    else:  # bad username entered
        print("invalid UserName, try again")
        print(f"you entered <{user_name}> for the username and <{user_pword}> for password")
        user_name = input("enter user_name or Q to quit: ")
        user_pword = input("enter password: ")

##  turn above into a function
##  add in three attempts and account is locked (how could you do that?)
