Install Python on Windows

Follow these steps to install Python 3 on Windows 10 or 11. The process takes about 5 minutes and gives you a fully working Python environment with pip (package manager) included.

Step-by-Step Installation

  1. Download the installer: Visit python.org/downloads and click the large yellow "Download Python 3.x.x" button. It auto-detects Windows.
  2. Run the installer: Double-click the downloaded .exe file.
  3. IMPORTANT: Check "Add python.exe to PATH" at the bottom of the first screen before clicking anything else.
  4. Click "Install Now": This installs Python, pip, IDLE, and documentation to the default location.
  5. Wait for completion: You'll see "Setup was successful" when done. Click Close.
Critical: If you forget to check "Add to PATH", you will get python: command not found errors. You would need to uninstall and reinstall, or manually add Python to your system PATH.

Verify Installation

Command Prompt (cmd)
# Open Command Prompt (Win+R, type cmd, Enter)
python --version
# Output: Python 3.12.1

# Check pip
pip --version
# Output: pip 23.3.1 from C:\Users\...\site-packages\pip (python 3.12)

# Run a quick test
python -c "print('Python is working!')"
# Output: Python is working!

First Program on Windows

hello.py
# Create a file called hello.py in any folder
# Open it with Notepad or VS Code and add:
print("Hello from Windows!")
print("Python is installed correctly.")

Run it from Command Prompt:

C:\Users\YourName> python hello.py
Hello from Windows!
Python is installed correctly.

Recommended: Install VS Code

  • Download Visual Studio Code (free)
  • Install the Python extension by Microsoft from the Extensions marketplace
  • VS Code gives you syntax highlighting, IntelliSense, debugging, and integrated terminal
  • Open any .py file and press Ctrl+Shift+` for the terminal, then run with python filename.py

Troubleshooting

ProblemSolution
python not recognisedReinstall with "Add to PATH" checked, or add manually via System > Environment Variables
Microsoft Store opens insteadDisable "App execution aliases" in Settings > Apps > Advanced app settings
pip not foundUse python -m pip --version instead
Permission errors with pipUse pip install --user packagename or run as administrator
Done! Python is installed on Windows. Next: learn to verify your installation thoroughly or jump straight to Hello World.

Frequently Asked Questions

Answers to common Python getting-started questions

You can use an online Python editor that runs in your browser. It provides a Python interpreter so you can execute code instantly without setup. This is ideal for quick practice and learning.

Download the latest Python installer from the official Python website, run the installer, and select "Add python.exe to PATH" before clicking "Install Now". After installation, verify with the command: python --version.

Download the macOS installer from the Python website, run it, and follow the steps. Verify the installation with python3 --version in the Terminal. macOS often uses python3 to refer to Python 3.

Open your terminal or command prompt and run python --version (Windows) or python3 --version (macOS/Linux). If you see a version number, Python is installed correctly.

On macOS and Linux, python may refer to Python 2.x while python3 refers to Python 3.x. Use python3 to ensure you are running Python 3.

Yes. Python runs on Windows, macOS, and Linux. Code is generally portable across platforms, especially for beginner-level scripts.
