I have some experience in Java, and I know that writing code to catch exceptions similar to what's shown in the video in Java would also present a scope issue since total_due is declared within the try statement.
Does the same apply to Python? Would total_due still be inaccessible before moving the amount_due line into an else statement?

Post back if you have more questions. Good luck!!

1,311 PointsI guess a better way of phrasing my question would have been "Is
total_dueusable outside of the try/except/else blocks?"Chris Freeman

Treehouse Moderator 68,426 PointsSince the assignment to
total_dueis not assigned within a function or class, it is in the namespace scope of the entire filecheck_please.py. This makes it accessible as a global variable anywhere within the file.Here's a short review of python scoping rules: https://stackoverflow.com/a/292502/2088339
