Can't enable Python bindings

[SulemanQB]

I can't enable Python bindings despite trying to replicate the original environment, Ubuntu 18, Python 2.7 and compatible versions of all libraries.

Also, I couldn't find these versions
REQUIRED_PYBINDGEN_VERSION = (0, 17, 0, 887)
REQUIRED_PYGCCXML_VERSION = (0, 9, 5)

Since wscript in the bindings/python folder states "Disable python in static builds (bug #1253)". What is the reason, release notes leave an empty line on bug #1253.

There is some issue with Pybindgen version since the required version couldn't be found; I tried changing the version needed to 17 and then configured successfully but without pybindgen (Error: not enabled (PyBindGen version not correct and newer version could not be retrieved)
).

If I use version 18 then it gives the following error. I tried 19, 20 and so on but same error.
