This might be a more broad question, and more related to understanding Python's nature and probably good programming practices in general.
I have a file, called util.py. It has a lot of different small functions I've collected over the past few months that are useful when doing various machine learning tasks.
My thinking is this: I'd like to continue adding important functions to this script as I go. As so, I will want to use import util.py often, now and in the future, in many unrelated projects.
But Python seems to feel like I should only be able to access the code in this file if it lives in my current directly, even if the functions in this file are useful for scripts in different directories. I sense some reason behind the way that works that I don't fully grasp; to me, it seems like I'll be forced to make unnecessary copies often.
If I should have to create a new copy of util.py every time I'm working from within a new directory, on a different project, it won't be long until I have many different version / iterations of this file, scattered all over my hard drive, in various states. I don't desire this degree of modularity in my programming -- for the sake of simplicity, repeatability, and clarity, I want only one file in only one location, accessible to many projects.
The question in a nutshell: What is the argument for Python to seemingly frown on importing from different directories?
