I am moving to Ubuntu 22.04 from Windows 10 and I was wondering if I could skip installing again all the packages I did on my Windows 10 machine on Python 2.7. Is it possible to save the package folders and paste them into the Python installation folder in Ubuntu?
It depends on what those packages contain. I wouldn't expect that 100% of packages would work, so if you want to save time (and frustration), then reinstall all packages for Linux, or run Python in a Windows VM or in Wine.
Details:
.dll files don't work on Linux. Linux has .so files (of different format) instead.
.pyc and .pyo files work only if the Python version and some compilation flags match exactly. This is unlikely: a random Python version (e.g. 2.7.x) on Windows won't match a random Python version (e.g. 2.7.y) on Linux.
.py files are usually system-independent, most of them will thus work unchanged.
