1. Introduction to Python
What is Python?: Python is a high-level, interpreted programming language known for its readability and simplicity. It is versatile and can be
used for web development, data science, automation, and more.
Python Syntax: Python’s syntax is straightforward, making it easy for beginners to learn. Indentation (whitespace) is important in Python to
define blocks of code, instead of braces {} used in many other languages.
2. Variables and Data Types
Python supports various data types, such as:
Strings (str): Sequences of characters enclosed in quotes.
Integers (int): Whole numbers.
Floats (float): Decimal numbers.
Booleans (bool): True or False.
Lists: Ordered, mutable collections of items.
Tuples: Ordered, immutable collections of items.
Dictionaries (dict): Unordered collections of key-value pairs.
3. Control Flow
Conditionals: if, elif, else statements allow you to execute code based on conditions.
Loops
:
for loop: Iterates over a sequence (like a list, tuple, or string).
while loop: Repeats as long as a condition is True.
, 4. Functions
Functions in Python are defined using the
def
keyword. Functions allow you to group code for reuse.

Copy code
def greet(name): return "Hello, " + name
5. Object-Oriented Programming (OOP)
Classes and Objects
: Python supports object-oriented programming, where you can define classes (blueprints for objects) and create objects (instances of
classes).
