Python How To: Colored text in the terminal

Python Programming


In programming, sometimes you need to print colored text to the terminal to make the output more readable or to highlight important information. Python provides several ways to do this.

ANSI Escape Codes

The most common way to print colored text in Python is to use ANSI escape codes. These codes are special sequences of characters that tell the terminal to change the color of the text.

Here’s an example of how to print colored text using ANSI escape codes:

print('\033[1;31;40mHello, World!\033[0m')

This will print “Hello, World!” in red text with a black background.

Let’s break down this code:

  • \033: This is the escape character that tells the terminal to start interpreting the ANSI escape codes.
  • [1;31;40m: This sequence of characters is the ANSI es...

Variables: Examples and explanations of Python variables.

Python Programming


In programming, a variable is a container that holds a value. The value can be a number, text, or any other type of data. Variables are useful because they allow you to store and manipulate data in your programs.

Naming Variables

To create a variable in Python, you first need to give it a name. The name of a variable should be descriptive and meaningful. It should also follow a few rules:

  • The name can only contain letters, numbers, and underscores.
  • The name cannot start with a number.
  • The name should not be a Python keyword, such as if, else, or for.

Here are some examples of valid variable names:

age = 42
name = “John”
is_student = True

Assigning Values to Variables

After you have named your variable, you can assign a value to it using t...
