Prep Python Project
Contents
Here is how I prepare python
projects.
Assuming Python3 is already installed
I uses python3
installed by default via OS package. or brew python3
(But if I have a chance to use conda
and the others, I may try)
Create python3 virtual environment
I uses venv
module
- Create
venv
1
python3 -m venv venv
- Activate
venv
1
source venv/bin/activate
- Here you have Isolated environment you can experiment, not affecting entire OS.

pip install --upgrade pip

pip-tools
