FYI: this is NOT a duplicate!
Before running my python code I installed biopython in the cmd prompt:
pip install biopython
I then
I could not import biopython when running python on windows.
I tried several solutions by changing the directory names to upper/lower case as https://stackoverflow.com/a/60753930/10884907 and also different way of calling when import using "Bio", "bio", "biopyhton". None was working.
But, It works in linux as simple as in manual guideliens, I did pip3 install biopython and with import Bio works!
