Simple code not working properly

[tmv]

RESOLVED Hello Python community,

I am currently learning Python, so forgive me if this question is stupid or something really obvious. I was doing a task in the Python Crash Course book, it is a simple if-else syntax, which for some reason doesn't work. I even asked multiple AIs, but they couldn't solve this issue. Here is the code:

usernames = []


if usernames:
    for username in usernames:
        if username == "admin":
            print(f"Welcome, Admin, do you wish to check the analytics?")
        elif username in usernames:
            print(f"Welcome, {username}, thanks for using our service.")
else:
    print("The list is empty!")

As you see, the usernames list is empty, but the print function in the else statement does not work. The output shows absolutely nothing. To make it clear, I always use the same device to code stuff and it works without any issues, and I am using the latest Python version.

Big thanks to everyone who is ready to help.

if not usernames:
   print('empty list')
else:
    print(usernames)

I don't understand the problem. When I run the posted code it prints "The list is empty!". Isn't that what you expect to see?

Maybe the indenting got fixed when you submitted your code. Did it look like this on your computer?

if usernames:
    for username in usernames:
        if username == "admin":
            print(f"Welcome, Admin, do you wish to check the analytics?")
        elif username in usernames:
            print(f"Welcome, {username}, thanks for using our service.")
    else:
        print("The list is empty!")

This code prints nothing if usernames is empty. In a for/else loop the else code is only executed if you break out of the loop.

This code does nothing useful.

elif username in usernames:

username is guaranteed to be in usernames. There is no reason to test.

There is no need for the f"" string in this command. You are not printing any variable values.

print(f"Welcome, Admin, do you wish to check the analytics?")
