Thanks to everyone who responded. I learned from each person's response.
The example code that I emailed was representative of many large programs that
I've written in other languages. I've written many small Python scripts and I'm
about to write a more complex Python script, much like the example

Really? Do you know why?
If you understand why then the measures to avoid them
become more palatable - the lesser of 2 evils.
Read-only globals are much less of a problem than read/write ones.
And in Python we l
Wow!
Quick response. I'll study the responses.
THANK YOU!

Global constants and variables are bad.
First, let me define my own "rule." Global constants should be all
uppercase, and global variables should be avoided. Trivial and buggy
scripts may ignore both rules. A trivial script is typic

Dear Tutor
Global constants and variables are bad. But what's better? I've heard some
suggestions, but haven't seen much actual code showing how to improve globals. I
don't like:
* Passing a lot of individual arguments.
* Creating a structure with unrelated elements.
* Passing a structure, as an
