Question:
My program is meant to show people their password for apps when they enter it, but for some reason its not showing all the app names they have entered in the line print('''here are your apps, {} which ones information do you want to view'''.format(a[0]) here if the user has previously entered their information for YouTube, Facebook etc., it should print out print(”’there are your apps, YouTube, Facebook
which ones information do you want to view”’.format(a[0]))
and then the user will type which one and it will show their password for it.

Answers:
The problem is in your existing_apps method. You are iterating over vault_apps but you are breaking once you have printed the first value.
I’ve added a modification where we get the list of names using a list comprehension, join it using join() and then print the values.
Note also a nice formatting trick where you can use f"{some_variable}" instead of "{}".format(variable)
