Python

Python is a popular general-purpose programming language that is especially suited to web development.

Install Python

sudo apt update -y
sudo apt -y install python3

Create a virtual environment

sudo apt -y install python3-venv
mkdir -p ~/bin/venv
python3 -m venv ~/bin/venv
source ~/bin/venv/bin/activate

Add the following to your .zshrc:

<<EOF>> ~/.zshrc cat
alias py-env="source ~/bin/venv/bin/activate"
alias py="source ~/bin/venv/bin/activate && python3"
EOF

Source the .zshrc:

source ~/.zshrc

And now you can activate the virtual environment by running:

py-env

Or run Python directly:

py

Use scripts

Create a script file, like hello.py:

print("Hello, World!")

Run the script:

py hello.py

Install Python packages

Assure you are in the virtual environment:

py-env

Install packages using pip:

pip install <package>

VSCode environment

For VSCode users, use Shift+Ctrl+P / Shift+Cmd+P and select Python: Select Interpreter to select local virtual environment, like /Users/$USER/bin/venv/bin.
