Do your eyes strain to read those tiny lines of code?

To kick things off: fonts. Head on over to the Options menu and select Configure IDLE. This will bring up a fancy window with all sorts of options that you can tweak to your heart’s content. Click on the Font tab, and voila! You’ll see a preview of what your code will look like in different font styles and sizes.

Now, let me tell you something: if you want to make your eyes bleed, go ahead and choose Comic Sans as your font. But for those who prefer something more professional-looking, I recommend sticking with monospaced fonts such as Courier New or Consolas. These will ensure that each character takes up the same amount of space on the screen, making it easier to read long lines of code without having to scroll left and right like a madman.

Once you’ve selected your preferred font style and size, click Apply to preview how it looks in action. If everything is looking good, go ahead and hit OK to save your changes. And if you ever want to reset things back to their default settings, simply select Reset Fonts from the same menu.

Now highlights. This feature allows you to customize the colors of different Python constructs such as keywords, strings, comments, and more. By default, IDLE uses a color scheme that is based on the colors in the Python logo (which I must admit looks pretty cool). But if you want to switch things up or create your own custom theme, head over to the Highlights tab in Configure IDLE.

Here, you’ll see a list of all the different constructs and their corresponding color codes. You can either select one of the pre-installed themes (such as IDLE Day, IDLE Night, or IDLE New) or create your own custom theme by clicking on Add Theme at the bottom of the window.

To add a new highlight rule, simply click on Add Rule and fill in the details such as the keyword or construct you want to highlight, its corresponding color code (in hexadecimal format), and whether it should be bolded or italicized. Once you’ve added all your desired rules, hit Apply to preview how they look in action. If everything is looking good, go ahead and hit OK to save your changes.

And that’s it! You now have a customized IDLE experience with fonts and highlights tailored to your liking.
