Introduction to Python

Python is a high-level, interpreted programming language that is known for its simplicity and readability. It is widely used for web development, data analysis, artificial intelligence, and much more. Python's design philosophy emphasizes code readability with its notable use of significant whitespace.

Basic Syntax and Structure

Python uses indentation to define the scope of its blocks, which makes it very easy to read and understand. Here's a simple example:

print("Hello, World!")

Variables and Data Types

In Python, variables are dynamically typed, meaning you don't need to declare the type of a variable explicitly. Here are some common data types:

  • Numbers: int, float, complex
  • Strings: str
  • Booleans: bool
x = 10  # Integer
y = 5.5 # Float
name = "Alice" # String
is_valid = True # Boolean

Control Flow

Python uses if statements for conditional execution and loops for iteration. Here's an example of a simple if statement:

if x > 10:
    print("x is greater than 10")

Functions

Functions are blocks of code that perform a specific task. You can define your own functions or use built-in functions. Here's an example of a custom function:

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

print(greet("Alice"))

Modules and Packages

Python modules and packages are collections of Python code. You can import them into your script to use their functions and classes. Here's an example of importing a module:

import math

print(math.sqrt(16))
