Installing Python

For this course, installing Python locally is optional: all suggested tasks run on our servers, and any custom Python code can be executed in the Sandbox.

If you still want to run code locally, here is a short installation guide.

In this quick guide you will install the latest Python 3 for your system and verify everything works. Let’s go! 🚀

Step 1. Check if Python is already installed

Open your terminal/console and check the version commands.

• Windows (PowerShell or CMD):

  Python 3.13
  python --version
  py --version
  pip --version
  

• macOS / Linux (Terminal):

  Python 3.13
  python3 --version
  pip3 --version
  

If you see a version (e.g., Python 3.12.x), Python is already installed. If commands are not found — proceed to installation.

Windows installation

1. Download the official installer: python.org → Downloads → Windows.
2. Run the installer.
3. On the first screen, tick “Add python.exe to PATH” (important!) and click Install Now.
4. Wait for completion and close the installer.
5. Verify in PowerShell/CMD:

Python 3.13
py --version
python --version
pip --version

If python is not found, try py, or sign out/in. Reboot if necessary.

macOS installation

Two convenient options — pick one.

Option A: Official installer

1. Download from python.org → Downloads → macOS.
2. Open the .pkg and follow the installer.
3. Verify versions:

Python 3.13
python3 --version
pip3 --version

Option B: Homebrew

1. Make sure Homebrew is installed (brew -v). If not, follow brew.sh.
2. Install Python:

Python 3.13
brew install python

3. Verify versions:

Python 3.13
python3 --version
pip3 --version

Note: on macOS, the python3 command (not python) is standard — this is expected.

Linux installation

Open Terminal and run commands for your distribution.

• Ubuntu / Debian:

  Python 3.13
  sudo apt update
  sudo apt install -y python3 python3-pip
  

• Fedora:

  Python 3.13
  sudo dnf install -y python3 python3-pip
  

• Arch Linux:

  Python 3.13
  sudo pacman -S python python-pip
  

Verify versions:

Python 3.13
python3 --version
pip3 --version

FAQ

• python command not found. On Windows try py. On macOS/Linux use python3 and pip3 — that’s normal.

• Upgrade pip:

  Python 3.13
  python -m pip install --upgrade pip
  # or
  python3 -m pip install --upgrade pip
  

Good luck with learning Python! ✨
