If you assign to a variable in a function, Python assumes that it’s local to that function unless you declare in that function that it’s global or nonlocal.

When you say
user_name = input("Enter Username: ")

Then the text "Enter Username: " just sets the text to be
displayed as information for the user about what to enter.

The returned value in user_name contains only what the user actually
typed in.

Glancing at your previous posts, I think you should learn about
function parameters and return values.
