Hi I'm new to python and I'm currently working on a python login programm for school. this is what I have so far:
The thing is when I intentionally type in a password or username wrong, I want the programm to type out username or password invalid. However it prints it out twice or thrice. This is because of the for loop that is going through my list and checking if the object's name or password are correct. If it's not it'll print out invalid etc. It does this twice or thrice. My question is: How can I make my programm type username or password invalid once? (btw I'm new to python, so go easy on me)
Thanks!
