I'm currently working on a sign-in system where users enter a PIN to access their bank account. The code is supposed to ask for the PIN, and once entered correctly, it should display a menu of options. However, even when the correct PIN is entered, the menu keeps printing infinitely in the console. I've made sure that entering an incorrect PIN triggers the intended behavior, but I'm stuck on this looping issue. Any advice on how to fix it?

It seems like your issue with the infinite loop might be happening because you're trying to use 'cmd' both as a variable and for input. Before you get into the menu, make sure you've initialized 'cmd' properly. If it's not defined before being used in the loop, that could cause problems. I recommend checking how you're handling variable names to avoid conflicts. You've got this; just a little tweak should solve it!
You're right to notice that the loop where you ask for the user's action isn't working right. It looks like your main menu might not execute correctly if 'cmd' isn’t checked properly. You should ensure that the command input is handled inside your loop without causing conflicts. Maybe try splitting the logic up a bit to clarify each part of the process!
I noticed that your use of 'cmd' might be causing some confusion since it's also a class in Python. Consider renaming your variable to something clearer like 'user_action'. Keeping variable and class names distinct can really help avoid issues like naming collisions. Once you do that, your code might start running a lot cleaner!
Good point! I always thought 'cmd' was a suitable shorthand, but I see how that can lead to problems. I'll try renaming it and see if it clears things up.
Thanks for the advice! I didn't realize initializing 'cmd' was necessary before the loop. I'll give that a shot.
