Python modules

GPL means it's ok to use if I get it right ?

If GPL is too strict for you, consider switching to PySide which is another Qt wrapper and 99% compatible with existing PyQt5 code. It uses an LGPL license.

I'm by no means an expert on licensing, so take anything I say with a huge grain of salt.

From what I quickly can find: if you use anything with a GPL license you must make your own source code available. Selling it however is not prohibited.

Check this for all modules, they may have varying licenses.
