I. Introduction

Today, I will guide you through the process of installing Python on your computer and using command-line python and IDLE.

Python’s official website is https://www.python.org/.
Navigate to the “Downloads” section by clicking the corresponding link in the navigation bar.
Click the “Download Python 3.12.0” button
Click the “Download Immediately” button to download the Python installer to the designated location on my computer.

Note that the ‘Add Python.exe to Path’ checkbox is checked.
Click the “Customize installation” option
Keep the Optional Features unchanged. And then click the “Next” button.
Enter the new path D:\Python\Python312 in the ‘Customize install location’ textbox.
Click the “Install” button to initiate the installation process.

When the installation is complete, you will see the message “Setup was successful” in the installation window.
Now let’s check where Python is installed.
python.exe is used for the command-line window, while pythonw.exe is utilized for the IDLE window.

Click the “Start Menu” button to open the start menu.
Click the “Python 3.12 (64-bit)” option to launch the Python command-line window.

Let me perform addition using Python statements.
Note that Python has three types of formatted printing: % formatting, the format() function, and f-strings.

Click on the File menu in the IDLE code window.
Choose the “Save As…” option.
Navigate to the location where you want to save the file.
Enter a suitable file name with the “.py” extension (e.g., “addition.py”).
Click the “Save” button. Now, your Python program is saved at the specified location with the given file name.

Open IDLE (Python GUI) on your computer.
Open a Python program stored on my disk
Choose the Python program at the designated location
Click the “Open” button
Press the F5 key or select “Run Module” from the “Run” menu. By doing this, IDLE will execute your Python script, and you should see the output in the interactive shell window. If there are no errors, your program will run successfully.

Installing Python is a straightforward process that ensures a clean and functional Python environment on your computer.
Always use the official Python installer and follow recommended procedures for a hassle-free experience.
