Python

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

Install Python

Debian/Ubuntu

sudo apt update -y
sudo apt -y install python3
sudo apt -y install python3-venv

macOS

brew install python@3.14
brew link python@3.14 --force --overwrite

Check Python version

python --version

In some cases, old Python version can take priority on new version:

Python 3.9.6

output

Here a solution for macOS with Homebrew:

export PATH="/opt/homebrew/opt/python@3.14/bin:$PATH"

~/.zshrc

Reload your PATH:

source ~/.zshrc
python --version

Now Python v3.14 by Homebrew will be used. If not works, check where is your Python version:

which python3
# OR
which python

Create a virtual environment

# 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:

# export PATH="/opt/homebrew/opt/python@3.14/bin:$PATH" # in some cases for macOS
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.
