==== Virtual environments ====

==What is a Virtual Environment?==

A virtual environment is an isolated directory that contains its own Python interpreter, libraries, and packages. It allows you to manage project dependencies independently, preventing conflicts with other projects or system-wide Python installations.


<sxh shell>
# create the virtual environment
python3 -m venv .venv

# activate it
source .venv/bin/activate

# this should point to the python binary in your virtual environment
which python

# install dependencies in the virtual env
python -m pip install -r requirements.txt
</sxh>
