How to Change Color of Text in Python

Changing text color in Python enhances the visual appeal and readability of your output, especially useful for highlighting important information or creating visually engaging applications. This guide provides a comprehensive overview of various techniques to achieve this, catering to different environments and output destinations.

Coloring Text in the Terminal using ANSI Escape Codes

One of the most common ways to change text color in Python within the terminal involves using ANSI escape codes. These special sequences of characters control the terminal’s display properties, including text color, background color, and formatting.

def color_text(text, color_code):
    return f"33[{color_code}m{text}33[0m"

print(color_text("This is red text", 31)) # Red
print(color_text("This is green text", 32)) # Green
print(color_text("This is blue text", 34)) # Blue

The 33[ initiates the escape sequence, followed by a color code and m. The 33[0m at the end resets the color to the default. how to print colored text in python provides further details on utilizing ANSI escape codes for varied color outputs.

Common ANSI Color Codes

  • 30: Black
  • 31: Red
  • 32: Green
  • 33: Yellow
  • 34: Blue
  • 35: Magenta
  • 36: Cyan
  • 37: White

Changing Text Color in Jupyter Notebook

Jupyter Notebooks offer a slightly different approach how to change text color in jupyter notebook. You can utilize HTML styling within Markdown cells to achieve colored text.

<font color="red">This text is red</font>
<font color="blue">This text is blue</font>

Advanced Techniques for Specific Applications

Several libraries extend Python’s capabilities for more specialized text coloring scenarios. For instance, the colorama library simplifies cross-platform ANSI code usage, while libraries like rich offer rich text formatting and styling for console output.

from rich import print

print("[red]This is red text[/red]")
print("[blue]This is blue text[/blue]")

If you are dealing with changing cell colors based on their values, how to change cell color based on value offers valuable insights.

“Color coding is fundamental for visualizing data effectively,” says Dr. Anya Sharma, Data Visualization Specialist. “It draws attention to critical patterns and makes complex information more accessible.”

Conclusion

Mastering How To Change Color Of Text In Python empowers you to create more informative and visually appealing outputs. From basic ANSI codes to specialized libraries like rich, choosing the right method depends on your specific needs and target environment. Understanding these techniques elevates your Python programming skills, enhancing your ability to communicate data and create engaging user interfaces. how to change text color in python provides a centralized resource for further exploration.
