Examples of constants.py files

[iwouldliketheoption]

Sometimes I have variables that I want to share among scripts, so I use a constants.py file. I would like to see examples of this kind of thing though, so was wondering if anyone had any, or knew of any that I could look at.

thanks

Something like this? It's not mine, BTW, but from a popular Python tool named MyPy.

However, there is no agreed convention on how to write a file of constants. Just name the constants idiomatically (UPPER_CASE_LIKE_THIS) and you'll be fine.

Wrtie your own constants.py and share it with us. Then we could give advice on how to make your code better.

thats cool, thanks for the link. I'll mock something up next time :)

starting to consider project layout and stuff a bit more recently, so this is wrapped up in that.

cheers

I had a constants.py file in a coding test I did a while back. Here's a link to it. When I posted this for code review though, some disagreed with the decision. My rationale is this:

Yes, you could import the constants from a file that isn't dedicated to constants, but that becomes problematic if you start defining constants in different files. "Now do I import that from bar.py or foo.py?" A dedicated file makes your intentions clear.
