Welcome to our introduction to Python and its features! Python is
a popular, high-level programming language known for its
simplicity and readability. In this chapter, we will explore the key
features of Python and provide examples to help you get started.

"Python is a great language for beginners and experts alike," says
David Beazley, a well-known Python expert and author. "It's easy
to learn, yet powerful enough to handle complex tasks."

One of the key features of Python is its use of indentation to
denote blocks of code. This makes the code easier to read and
understand. For example, the following code calculates the sum of
two numbers:

a = 5
b = 10
sum = a + b
print(sum)
In this code, the lines that are indented under the sum = a +
b line are considered to be part of the block of code that
calculates the sum. This makes the code easy to follow and
understand.

Python also has a large standard library, which includes modules
for working with files, interacting with the operating system, and
more. For example, the following code uses the os module to
print the current working directory:

import os
print(os.getcwd())
