python multiple imports for a common module

Question

I am working on a project wherein I need to use a third party module in different project files(.py files). The situation is like this.

I have a file "abc.py" which imports third party module "common.py". There are couple of other files which also import "common.py". All these files are also imported in main project file "main.py".

It seems redundant to import same module in your project multiple times in different files since "main.py" is also importing all the project files.

I am also not sure how the size of the project gets affected by multiple import statements.

Can someone pls help me in making things bit simpler.

Answer 1

Importing only ever loads a module once. Any imports after that simply add it to the current namespace.

Just import things in the files you need them to be available and let Python do the heavy-lifting of figuring out loading the modules.
