Quick Python 8: Virtual Environments

In this video, we learn how to create, manage, and remove Python Virtual Environments.

Here’s a link to the source code.

Quick Tips

Commands

python3 -m venv <path>

Creates a virutal environment located at <path>

source <path>/bin/activate

Activates a virtual environment

deactivate

Deactivates a virutal environment

Bonus: Bash Alias for Quick Switching

Paste this function into your ~/.bashrc or ~/.bash_aliases file and restart your shell. It assumes you keep your virtual environments in the ~/venv folder.

venv() {
    source ~/venv/$1/bin/activate
}

Switch to the venv with venv <NAME> and get out of it by typing deactivate.

Example:

python3 -m venv ~/venv/my-env
venv my-env
# do stuff in your environment. When done:
deactivate
