Let’s suppose there’s a company abc that makes a library abc.

I’d like to make a Python package that interfaces with abc.

I could just call it abc. However, that seems selfish to take that name in case the company itself wants to publish a package using that name.

Alternatively, I could incorporate my username:

dharmatech_abc

Or:

dharmatech.abc

Question

If I go the username approach, which of the above is more idiomatic in Python packaging? Underscore or .?

If I decide to publish my package to pypi, and I went with the . approach, would the package be called dharmatech.abc?

If I go with the . approach, and I have other packages that also start with my username, will it be a problem that multiple separate packages all contribute to that dharmatech top level namespace?
