Pardon me for not using the proper Python language terms, but I hope
that people can still understand the question:
The problem: I'm writing a large Python program and I have a bunch of
parameters (whose values are static) that I want to make available to
the rest of the code with minimum overhead and duplicate processing.
I think that the simplest way would be to create a file called
"Params.py" and then simply have statements like a = 1, b = 2, etc.
in there (no classes, no methods, just a bunch of declarations). But,
some of these static parameters have to be calculated rather than simply
I thought of creating a class called Params and having a bunch of
methods (decorated with @classmethod) that set/calculate the value of
all the parameters. Easy enough, but then I have to create a Params
object in every source file that uses these parameters, and that seems
The actual scope of the problem is very small, so memory/cpu time is not
an issue. I'm just looking for the most pythonic/elegant way of doing this.
What is the recommended way of passing a bunch of static (hard-coded and
calculated) parameters to various parts of the code?
Thank you for any advice,
