Check pre‑installed Python version

Open Terminal (⌘+Space, type “Terminal”) and run python3 --version. If a version such as Python 3.x.x appears, Python 3 is already present; otherwise you need to install it.

If a dialog asks to install the Command Line Tools, click “Install” and wait for the download.

Install Homebrew (macOS package manager)

Run the following command in Terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Follow the on‑screen prompts, entering your password when requested.

Verify the installation with brew --version. If an older version is reported, update Homebrew:

brew update

In Terminal run: brew install python Wait for the process to finish, then confirm the installed version (e.g., Python 3.13) with: python3.13 --version Check that pip is available:

pip3 --version

Add Python to PATH (if necessary)

Edit your shell profile ( ~/.zshrc for Zsh or ~/.bash_profile for Bash) and append:

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

Save the file and reload the profile: source ~/.zshrc Verify the change with python3 --version.

Install optional Python libraries

Common libraries include NumPy, Pandas, Flask, and Matplotlib. Install any library with:

pip3 install library_name

Choose an IDE (optional)

Beginner‑friendly IDEs: GeeksforGeeks IDE, Visual Studio Code, PyCharm.
