In Python, you can print colored text to the terminal using several methods. Here are the most popular approaches:

1. Using ANSI Escape Codes

ANSI escape codes are special sequences used to control text formatting, including color, boldness, and background.

Syntax:

print("\033[<style>;<text-color>;<background-color>mYour Text\033[0m")

• \033[ : Escape sequence to start.
• m : Ends the color/style formatting.
• 0 resets the style after the colored text.

Example:

1# Colored text using ANSI escape codes
2print("\033[31mThis is red text\033[0m")  # 31 = red
3print("\033[32mThis is green text\033[0m")  # 32 = green
4print("\033[33mThis is yellow text\033[0m")  # 33 = yellow
5print("\033[34mThis is blue text\033[0m")  # 34 = blue
6print("\033[1;35mThis is bold magenta text\033[0m")  # 1 = bold, 35 = magenta
7print("\033[1;37;44mWhite text on blue background\033[0m")  # 37 = white text, 44 = blue background

Common Codes:

• Text Colors:
  • 30: Black, 31: Red, 32: Green, 33: Yellow
  • 34: Blue, 35: Magenta, 36: Cyan, 37: White
• Styles:
  • 0: Reset, 1: Bold, 4: Underline, 7: Inverted colors
• Background Colors:
  • 40: Black, 41: Red, 42: Green, 43: Yellow
  • 44: Blue, 45: Magenta, 46: Cyan, 47: White

2. Using the colorama Library (Cross-Platform)

colorama is a library that makes it easy to print colored text in a cross-platform way, especially on Windows where ANSI codes are not natively supported.

Installation:

pip install colorama

Example:

1from colorama import init, Fore, Back, Style
2
3# Initialize colorama (required for Windows)
4init(autoreset=True)
5
6# Print colored text
7print(Fore.RED + "This is red text")
8print(Fore.GREEN + "This is green text")
9print(Back.YELLOW + "Yellow background")
10print(Style.BRIGHT + Fore.BLUE + "Bright blue text")
11print(Fore.WHITE + Back.BLUE + "White text on blue background")

Output:

• Fore sets text color.
• Back sets background color.
• Style adds effects like bold (e.g., Style.BRIGHT).

3. Using the termcolor Library

termcolor simplifies adding colors to terminal text.

Installation:

pip install termcolor

Example:

1from termcolor import colored
2
3# Print colored text
4print(colored("This is red text", "red"))
5print(colored("This is green text", "green"))
6print(colored("Yellow text on blue background", "yellow", "on_blue"))
7print(colored("Magenta text with bold style", "magenta", attrs=["bold"]))

Output:

• colored(text, color, on_color, attrs) formats the text.
• Supported colors: 'red', 'green', 'yellow', 'blue', 'magenta', 'cyan', 'white'.

4. Using the rich Library (Advanced Features)

rich is a powerful library for rich text formatting, including color, bold, tables, and progress bars.

Installation:

pip install rich

Example:

1from rich.console import Console
2
3console = Console()
4
5# Print colored text
6console.print("This is [bold red]red and bold[/] text")
7console.print("This is [green]green[/] text")
8console.print("This is [yellow on blue]yellow text on blue background[/]")

Output:

rich uses a markup syntax similar to HTML for text formatting.

Summary Table

Recommendation:

• Use colorama for basic, cross-platform terminal colors.
• Use rich for advanced text formatting and terminal enhancements.
• Use ANSI escape codes for quick, lightweight color changes without libraries. 🚀
