Key Features of Python:

Basic Syntax

Python uses indentation to define blocks of code, which helps maintain a clean structure. Here’s a simple example:

if True:
    print("This is a block of code.")

Python Examples:

Here are some basic examples of Python code:

1. Hello World

print("Hello, World!")

2. Simple Calculator


# This function adds two numbers
def add(a, b):
    return a + b

# Example usage
result = add(5, 3)
print("The sum is:", result)
    

3. Factorial Calculation


# Function to calculate factorial
def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)

# Example usage
print(factorial(5))  # Output: 120
    

Data Types in Python

Python supports various data types, including:

Control Flow

Python uses control flow statements such as if, for, and while to control the execution of code:

for i in range(5):
    print(i)

Functions in Python

Functions are defined using the def keyword:

def greet(name):
    return f"Hello, {name}!"

print(greet("Alice"))  # Output: Hello, Alice!

Common Libraries

Some popular libraries include:
