Python is a powerful and versatile programming language widely used for web development, automation, data analysis, and more. To get started with Python on Windows, you need to install both Python itself and PIP (Python Package Installer), which allows you to manage additional Python libraries easily. In this guide, we will walk you through installing Python and PIP on a Windows system, as well as demonstrating how to use them effectively.

Download Python Installer

  1. Open your browser and go to the official Python website.
  2. Click on the latest stable version of Python available (preferably Python 3.x).
  3. Download the Windows Installer (64-bit) unless your system specifically requires the 32-bit version.

Install Python on Windows

  1. Locate the downloaded python-3.x.x.exe file in your Downloads folder.
  2. Double-click the installer to launch the installation wizard.
  3. Important: Check the box “Add Python to PATH” before proceeding.
  4. Click Install Now and wait for the installation to complete.
  5. Once the installation finishes, click Close.

To verify that Python was installed successfully, open Command Prompt (cmd) and run:

python --version

If installed correctly, it should output something like:

Python 3.x.x

Verify and Install PIP

PIP (Python Package Installer) is included by default with most versions of Python 3. To check if PIP is installed, run:

pip --version

If you see an output like:

pip 21.0.1 from C:\Users\YourUser\AppData\Local\Programs\Python\Python39\lib\site-packages\pip (python 3.9)

PIP is already installed.

If PIP is missing, install it manually using:

python -m ensurepip --default-pip

To upgrade PIP to the latest version, use:

python -m pip install --upgrade pip

Using PIP to Install Python Packages

Once Python and PIP are set up, you can install additional Python libraries using PIP. Here are some examples:

Installing a Package

To install a package (e.g., NumPy for numerical computing), run:

pip install numpy

Installing Multiple Packages

If you need multiple packages, list them in a requirements.txt file and install them using:

pip install -r requirements.txt

Checking Installed Packages

To see a list of installed packages, use:

pip list

Uninstalling a Package

To remove a package, run:

pip uninstall numpy

Running Python Scripts

To execute a Python script, follow these steps:

  1. Open a text editor (e.g., Notepad++ or VS Code) and create a new file.
  2. Write your Python code, for example:
    print("Hello, Python on Windows!")
  3. Save the file as hello.py in a convenient location.
  4. Open Command Prompt and navigate to the directory where you saved the file using cd:
    cd path\to\your\file
  5. Run the script with:
    python hello.py

    You should see:

    Hello, Python on Windows!

Conclusion

Congratulations! You have successfully installed Python and PIP on your Windows machine. You are now ready to explore the world of Python programming and install additional libraries as needed. Whether you’re working on data science, web development, or automation, Python is a great tool to have at your disposal.
