Course Summary

Python is a high-level, interpreted, dynamically-typed language known for its clean syntax and versatility. It is used in web development, data science, automation, AI, and more.

Key Python Features

• Easy to read — indentation-based syntax, no braces
• Interpreted — runs line by line, no compile step
• Dynamically typed — no need to declare variable types
• Object-oriented — everything is an object
• Huge standard library — batteries included
• Cross-platform — runs on Windows, macOS, Linux

Quick Reference

# Variables
name = "Python"
version = 3.12
is_fun = True

# String formatting
print(f"Hello from {name} {version}!")

# List, tuple, set, dict
my_list  = [1, 2, 3]
my_tuple = (1, 2, 3)
my_set   = {1, 2, 3}
my_dict  = {"key": "value"}

# Control flow
for i in range(5):
    if i % 2 == 0:
        print(f"{i} is even")

# Function
def greet(name="World"):
    return f"Hello, {name}!"

# Class
class Animal:
    def __init__(self, name):
        self.name = name
    def speak(self):
        return f"{self.name} makes a sound"

# Lambda
square = lambda x: x ** 2

# Comprehension
evens = [x for x in range(10) if x % 2 == 0]

# Generator
def count_up(n):
    for i in range(n):
        yield i

# Decorator
def logger(func):
    def wrapper(*args, **kwargs):
        print(f"Calling {func.__name__}")
        return func(*args, **kwargs)
    return wrapper
