Create "reverse engineered" python wheel from a package installed via pip that is not on a package index like PyPi

Question

The question might sound a bit weird because creating wheels is standard Python knowledge.

We have the special situation that we have numerous different Python environments with an unversioned package my_package that was installed some time ago. So we have multiple installations of this package with different underlying code bases.

Now the problem is that we want to re-use this package in another project. Thus, my idea was to create a "reverse engineered" wheel.

Let's say I have:

$ pip list
Package                            Version
---------------------------------- -------------------
aiohttp                            3.7.4.post0
my_package                         0.0.1
alembic                            1.7.1

and want to create a wheel from my_package and possibly the other packages in the environment.

Thanks in advance for your help!
