I. Introduction
- Today, I will guide you through the process of installing Python on your computer and using command-line python and IDLE.
II. Installing Python
1. Download the latest version of Python from the official website
- 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.
2. Run the installer and follow the installation wizard
- Choose Customize to enable or disable features
3. Ensure that the “Add Python.exe to PATH” checkbox is checked for easier command-line access
- Note that the ‘Add Python.exe to Path’ checkbox is checked.

4. Complete 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, whilepythonw.exe
is utilized for the IDLE window.
III. Using Command-Line Python for Fun
1. Open the command-line Python from the start menu
- 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.
2. Use the print function to display a message on the screen
- Display a message “Welcome to Python World~”
3. Perform basic operations, such as addition, using Python statements
- Let me perform addition using Python statements.
- Note that Python has three types of formatted printing: % formatting, the format() function, and f-strings.
4. Type exit() and press Enter to quit the command-line Python
- Type exit() function
- Press Enter to quit the commad-line Python
IV. Using Python with IDLE Window
1. Open the IDLE Python from the start menu
- Click the “Start Menu” button to open the start menu.
- Click the “IDLE (Python 3.12 64-bit)” option to open the Python IDLE window.
2. Perform operations interactively
- Let me perform addition using Python statements.
3. Write a Python program in the IDLE code editor window
- Click the “File” menu and choose “New File…” to open an IDLE code window.
- Write a program to perform the addition of two numbers.
4. Save the Python program at the spciefied location
- 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.
5. Run a Python program in IDLE
- 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.
V. Conclusion
- 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.
