How to import local files which import local files themselves? (kbin.earth)

With a project structure like this:

├─main.py
└─src
    ├─dep1.py
    └─dep2.py

where the contents of each file is as follows:

main.py: import src.dep1 as firstdep; print("Total success")

dep1.py: import dep2 as seconddeb; print("success 1/3")

dep2.py: print("success 2/3")

Is the best way to do this creating an __init__.py file in src and importing src.dep2 in dep1.py? or is this a bad idea?

Yeah, that's the solution I asked about (last line of my question). I was just trying to make sure that this is ok and won't tangle up my code later on.

I'm not sure why you're using as to make the module name longer? Usually, if I use it at all, I use it make things shorter. Anyway, once you've imported dep2, you can call dep2.some_fn().

That was just for the example (clarifying order of import). The actual code has imports such as from src.formatter import Formatter as fmt; always making the name shorter.

Thanks for the suggestions

    I was just trying to make sure that this is ok and won’t tangle up my code later on.

    I guess the main issue there is Python doesn't like circular dependencies? Like if you try to import dep2 from dep1 and dep1 from dep2, you're going to have a problem. You'd essentially have to refactor your code to have a dep3 that both can import to use the common functionality I guess.
