How to list the names of PyPI packages corresponding to imports in a script?

Question

Is there a way to list the PyPi package names which correspond to modules being imported in a script?

For instance to import the module scapy3k (this is its name) I need to use

import scapy.all

but the actual package to install is scapy-python3. The latter is what I am looking to extract from what I will find in the import statement (I do not care about its name - scapy3k in that case).

There are other examples (which escape me right now) of packages which have a pip install name completely different from what is being used in the import afterwards.

Answer 1

The name listed on pypi is the name defined in the distribution's setup.py / setup.cfg file. There is no requirement that this name relates to the name of the package that will be installed. So there is no 100% reliable way to obtain the name of a distribution on pypi, given only the name of the package that it installs (the use case identified in the OP's comment).
