I programmed a python file that allows you to register (Name, Password, EMail (with Confirmation EMail sent to you with a code)) and after you are registered your data is being saved in a seperate text file now I want python to check when you enter your username whether the username already exists or not.
There is this names.txt file and it is just 1Line: Username 2Line: Password 3Line: email adress when you register a new enter code here unt it will show the same below the first account in the txt file. But I want python to check this text file now during your registration whether you can use this username because its not used so far, or if the username already exists and you have to take another one.
