How to create a PyCharm project
The first time you run PyCharm you need to configure the PyCharm interpreter with python 3.7 because PyCharm defaults to the Grids base interpreter.
- On the welcome screen, select New Project.
- Set the interpreter type to Custom environment. The first time you launch PyCharm, set the environment to Generate new, set the type to Virtualenv, and set the base python to /usr/bin/python3.6. Once this is done, click Create. Note: Despite it saying the base python is 3.6, it will update to the 3.7 interpreter.
- Now that 3.7 is configured, for future projects please choose the Custom environment interpreter, and set the environment to Select existing. There you will be able to select Python 3.7.3 for your python path. Lastly, select Create.
