        accounts.append(f"{username}|{password}")

code

on line for account in accounts

i would like it to only check the part before the | on each line so that it doesnt also read the password. how could i go about doing this?

[remote prawn]

You need to parse the line into the parts you need. The easiest way to do that here is to just use the string's split method to split the line on the | character.

[dapper badger]

so

[remote prawn]

Or use the CSV module since if your format is CSV with pipes.

[dapper badger]

for account in accounts.readline().split(" |")

[remote prawn]

You'd just iterate accounts like you were doing (but without the () at the end of accounts). Then split account.

[dapper badger]

def accountRegistration():
    global username
    with open("Accounts.json", "ar") as accounts:
        if username == "":
            username = takeInput(str, "\nPlease select a username. must be unique. > ")
            for account in accounts:
                if account.split(" |") == username:
                    username = ""
                    return "\nUsername in use."
        else:
            password = takeInput(str, "\nPlease input a password.")
            if validPassword:
                accounts.append(f"{username}|{password}")
                return passwordValidation
            else:
                return passwordValidation

looks good?

[remote prawn]

Did you try it?

[dapper badger]

not yet aha

its not implemented into the program as of yet

[remote prawn]

if account.split(" |") == username: think about what this is checking.

[dapper badger]

hmm

[remote prawn]

split returns a list.

[dapper badger]

usernamepass

ohh

if account.split(" |")[0] == username:

?

[remote prawn]

That looks better, ya. I'd move the split out for clarity though:

read_username, _ = account.split(" |")
# or just
# read_username = account.split(" |")[0]
if read_username == username:

And I think you want to remove that space in the string since it doesn't look like your files contain a space there.

[dapper badger]

done and done

thank you very much

[dapper badger]

Hi i am getting one more error when attempting to open /create the file "accounts.json" i get the error [must have exactly one of create/read/write/append mode

with open("Accounts.json", "ar") as accounts:

how do i open the file in append and read mode

so that i can scan the file whether the username is taken

as well as write to the file if i want to add to it

[remote prawn]

You're welcome. And see here: https://docs.python.org/3/library/functions.html#open
