Summary  
This chapter covers using Python comments (lines starting with #) to annotate code for improved readability and maintenance, explaining where to place inline and block comments along with best practices.  

General domain of usage  
Software development

As your codebase expands, it can become difficult to grasp every detail, even if you're the one who wrote it. That's why forming the habit of adding **comments** to your code is crucial. Comments make it easier to **understand the purpose or function of specific code segments**.

Watch this video to see how comments are used in Python code to improve readability. You'll learn where to place comments, how they help clarify your code, and best practices for writing helpful comments. This visual guide will reinforce why comments are essential for both you and anyone else reading your code.

To create a comment, simply begin the line with the `#` symbol. Any line that starts with `#` will be ignored by the Python interpreter and won't be executed.

# The `print()` statement below won't be executed
# print('This is a commented line')
print('This text will be printed')

Python is an interpreted high-level general-purpose programming language. Unlike HTML, CSS, and JavaScript, which are primarily used for web development, Python is versatile and can be used in various fields, including software development, data science, and back-end development. In this course, you'll explore the core aspects of Python, and by the end, you'll be crafting your own functions!

Dive into the basics of Python, explore your workspace, and perform simple math operations. Learn how to write readable code using comments and handle both basic and advanced mathematical expressions while displaying your results.
