It served me without problems for decades. So, I was wondering, whether somewhere in the growth of modules and options a weak spot is appearing...

Win32api problems
I recently installed IPython, Pandas, Altair, Jupyter, MatPlotLib, and Numpy on my Windows 10, Python27 installation to explore what it can do. When I tried to run my normal scripts a few days later, I discovered that win32com and related modules like win32ami give problems: Traceback (most recent call last): File "D:\gaudi\src\PythonTools\generateDocumentsPdf.py", line 10, in from win32com.client.dynamic import Dispatch File "C:\Python27\lib\site-packages\win32com\__init__.py", line 5, in import win32api, sys, os ImportError: DLL load failed: The specified procedure could not be found. after trying out several tips on Internet, like copying dll and pyd files, I re-installed my entire ActiveState installation. Luckily it works again. However, question is what culprit of my initial list damaged the Python-win32 configuration? Gerrit -- https://mail.python.org/mailman/listinfo/python-list
Python 2 EOL; what about P2 packages
I had missed the End-of-Life announcement of Python 2 for 2020. When installing a missing package on my new laptop, pip did warn me about this upcoming event. I have been reading up on the conversion. Unfortunately, I can find no information yet on coping with Python 2 only packages. So far, I identified that I am using at least 2 packages that are Python 2 only: + HTMLgen (the old original version that has been an orphan for decades; simple but effective) + eGenix (excellent package with a.o. MxDateTime; I can only find a sprint attempt to convert t to Python 3) Any suggestions how to port to Python 3, when using Python 2 only packages? Although the websites state that we can keep using Python 2 after maintenance stops, this may in practice not be the case. Any time that we need to get a new laptop operational, we need a way to install it. E.g. pip should stay working... Gerrit -- https://mail.python.org/mailman/listinfo/python-list
Re: PIL installation fails; registration problem
Some more searching brought me to Pillow. That seems to work! No answer needed anymore on previous question.
