- What OS and OS version are you running?
- What is the Python script you are trying to write?
- Do you get the same behavior if you try to save an empty file?
- Can you confirm you are talking about Idle, the editor t

I see two options for you:
1. put your scripts directly into "bustrac" (rather than a subdirectory)
There are too many files; the directory is very cluttered.

Isn't there an argument that in this context, using the single letter
"l" as a variable name is 'lazy'? That the "l" could be used in
different contexts (per OP). That it conveys no meaning as to the
variable's purpose?
In this specific case, I actually think that "l" is a bad choice, but

Not quite. The single-letter names mean "I am an iterator/index/etc",
but "_" means "I am not used anywhere".

Small addendum to this. pyflakes (at least in my experience) doesn't
interpret "_" as a variable name or prefix to a local variable as
"unused".

As of at least recent versions (I have 2.1.1 in my Conda install at
home) It seems to properly accept "_" as a variable name, even when
not used. It also seems to accept any variable name as a loop index.
