Python is a high-level, all-purpose programming language that is used extensively in data research, web development, and many other fields. Version 3 of Python, which is the current version, is the most recent version and includes several upgrades from earlier iterations.

To install Python 3 on a Windows computer, follow these steps:

  1. Open a web browser and go to the official Python website (https://www.python.org/).
  2. Click on the Downloads tab at the top of the page.
  3. Under the “Python Releases for Windows” section, click on the link for the latest version of Python 3 (3.9.0 at the time of writing).
  4. Download the Windows installer for the latest version of Python 3 by clicking on the appropriate link.
  5. Once the download is complete, run the installer.
  6. Follow the instructions on the screen to install Python on your computer.

It is recommended to select the option to “Add Python 3.9 to PATH” during the installation process. This will make it easier to run Python from the command line, as you won’t need to specify the full path to the Python executable every time.

Once the installation is complete, you can verify that Python is installed and working correctly by opening a command prompt or terminal window and running the following command:

				
					python --version

This should print the version number of Python that was installed on your system (e.g. “Python 3.9.0”).

Congratulations, you have successfully installed Python 3 on your Windows computer! You can now use Python to write and run your own programs.

First program "Hello World"

Once you are in the Python interpreter, you can start writing and executing Python code. Here is a simple example that shows how to print a message to the screen:

				
					# This is a comment. Comments are used to explain what the code is doing.
# They are ignored by the Python interpreter.

# Use the print() function to print a message to the screen
print("Hello, world!")

In Python, you can use the # symbol to indicate that the rest of the line is a comment. Comments are useful for explaining what your code is doing, and they are ignored by the Python interpreter.

The print() function is used to print a message to the screen. To use the print() function, you simply type print followed by the message you want to print in parentheses. For example, print("Hello, world!") will print the message “Hello, world!” to the screen.

That’s the basics of how to use Python! There is much more to learn, of course, but this should be enough to get you started. If you want to learn more, there are many resources available online, including tutorials, documentation, and forums where you can ask questions and get help from other Python users.


Thanks for reading. Happy coding!
