What is the best way to use python libraries in multiple code files?

Question

Python

I have libraries, I have code on several files: is it better to store imports in one file and call this file in each code file? I just don't know how to make it more convenient, because some libraries are needed in one file, others in another

Answer 1

Import as usual, in each file.
A generic file with imports will only complicate matters, but will not give any gain in code readability, since different files will require different modules.
I also advise you to follow the PEP8 standard in terms of the order of imports:
First imports of standard modules.
Then imports of third-party libraries (what I installed via pip).
Last but not least, module imports from your project.
Within each section, the elements can be ordered alphabetically, unless there is a particular reason to import them in a different order.

Answer 2

I 'll add to Vindicar 's words :
PEP also implies exporting the PATH environment variable .
Therefore, you can do:

PATHMYLIB='/path/to/my/libs:$PATH'
export PATHMYLIB
