I am trying to teach myself python. Using Windows 10 and the latest python as of July 2020. I installed anaconda and was able to run python code in the Jupyter notebook. It was able to find matplotlib, numpy, and other modules, both within Jupyter and at the anaconda prompt. But I am stubbornly insisting on using Pycharm. So I open pycharm and pycharm cannot find those modules. I opened pycharm in two ways (clicking on the desktop icon, and simply typing "pycharm" at the anaconda prompt). Doesn't matter. pycharm can't find modules either way.
I have read through a similar post "Module not found in PyCharm but externally in Python". There are numerous suggestions there. But none of them are really simple and straightforward. I know from using many other languages that there must be a simple and straightforward way that doesn't involve arcane BS like creating an virtual environment.
