Centering Text in the Python Terminal: A Common Formatting Dilemma

When working with terminal prints in Python, particularly if you're using colored text, you might run into an issue: the text fails to center as expected. This can be frustrating, especially if you're striving for a polished output. In this guide, we will explore the problem and provide a straightforward solution to ensure that your colored text appears perfectly centered in the terminal.

The Problem

Here’s what's happening. Imagine you want to print a sentence where part of it is colored for emphasis. You might try to center this text with the str.center() method, but to your surprise, it just doesn’t center as it should when you include colored text using the termcolor module. Here is the code causing the problem:

In this setup, you expect the complete message to be centered based on the total terminal width. However, when colored text is involved, the output seems misaligned. The core reason for this lies in how Python computes the string length when formatting outputs with colors.

The Solution

The good news is that there is a simple workaround to this issue. By changing the order in which color is applied and the string is formatted, you can achieve the desired outcome. Let’s break it down into easy steps:

1. Isolate the Colored Text

Instead of combining the colored segment with the rest of your message inside the print() function, first create the colored part separately. This allows Python to accurately measure the string length without the color formatting affecting it.

2. Use f-strings for Clarity

Using f-strings can make your code cleaner and more readable. Here’s the modified code you can use:

Key Points to Remember

Keep the Colored Segments Separate: By saving the colored text in a variable before formatting it into the full string, you can maintain the correct length.

Utilize f-strings: They not only make your code more intuitive but also handle string formatting in a modern way.

Test for Terminal Size: Always ensure the terminal size is fetched correctly using shutil.get_terminal_size() to make accurate calculations for centering.

Conclusion

With this solution, you’ll be able to center colored text in your Python terminal effortlessly. Simply remember to isolate your color application and use f-strings to construct your print statements. Now you can enhance your terminal output with aesthetically pleasing formatted messages that are both informative and attractively displayed.
