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

# For Ubuntu/Debian systems
sudo apt -y install python3-venv

# Create a virtual environment in your home directory
python3 -m venv ~/venv_python
# Activate the virtual environment
source ~/venv_python/bin/activate

Add the following to your .zshrc:

alias python="python3"
alias py-env="source ~/venv_python/bin/activate"
alias py="source ~/venv_python/bin/activate && python3"

Source the .zshrc:

source ~/.zshrc

And now you can activate the virtual environment by running:

py-env

Or run Python directly:

py

Upgrade pip

pip install --upgrade pip

Use scripts

Create a script file, like hello.py:

print("Hello, World!")

hello.py

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/venv_python/bin/python.
