Module 1: Introduction to Python

1.1 Overview of Python

Python is a high-level, interpreted programming language known for its readability and simplicity. It supports multiple programming paradigms, making it versatile and widely used in various domains.

1.2 Setting up Python Environment

Install Python from python.org.

Choose an Integrated Development Environment (IDE) like PyCharm or VSCode for coding.

1.3 Writing Your First Python Program

# hello_world.py

print("Hello, World!")

Save this file and run it using the command python hello_world.py. You should see the output "Hello, World!".

Module 2: Python Basics

2.1 Variables and Data Types

# variables_and_data_types.py

# Variables

name = "John"

age = 25

height = 5.9

# Data Types

print(type(name)) # <class 'str'>

print(type(age)) # <class 'int'>

print(type(height)) # <class 'float'>

2.2 Operators and Expressions

# operators_and_expressions.py

# Arithmetic Operators

result = 10 + 5 * 2 # 20

remainder = 15 % 7 # 1

# Comparison Operators

is_equal = (5 == 5) # True

not_equal = (10 != 5) # True

# Logical Operators

logical_and = (True and False) # False

logical_or = (True or False) # True

2.3 Control Flow

# control_flow.py

# If Statements

age = 18

if age >= 18:

    print("You are an adult.")

else:

    print("You are a minor.")

# Loops

for i in range(5):

    print(i)

# Output: 0 1 2 3 4

These examples provide a foundation for understanding Python fundamentals. Each subsequent module would build upon these concepts, delving into more advanced topics such as functions, data structures, and object-oriented programming. If you'd like more detailed examples or specific topics, feel free to ask!

Module 3: Functions and Modules

3.1 Defining and Using Functions

# functions.py

# Function Definition

def greet(name):

    return f"Hello, {name}!"

# Function Call

result = greet("Alice")

print(result) # Output: Hello, Alice!

3.2 Understanding Modules and Libraries

# modules_and_libraries.py

# Importing Modules

import math

# Using Module Functions

result = math.sqrt(25) # 5.0

print(result)

3.3 Exploring Built-in Functions and Standard Libraries

# built_in_functions.py

# Built-in Functions

print(len("Python")) # 6

print(max(3, 8, 2)) # 8

# Using Standard Libraries

import random

random_number = random.randint(1, 10)

print(random_number)

Module 4: Data Structures

4.1 Lists, Tuples, and Dictionaries

# data_structures.py

# Lists

fruits = ["apple", "banana", "orange"]

fruits.append("grape")

# Tuples

coordinates = (3, 5)

# Dictionaries

person = {"name": "John", "age": 25}

print(person["name"]) # Output: John

4.2 String Manipulation

# string_manipulation.py

# String Concatenation

greeting = "Hello"

name = "Alice"

full_greeting = greeting + ", " + name + "!"

# String Formatting

formatted_greeting = f"{greeting}, {name}!"

Module 5: File Handling

5.1 Reading from and Writing to Files

# file_handling.py

# Writing to a File

with open("example.txt", "w") as file:

    file.write("Hello, this is a sample text.")

# Reading from a File

with open("example.txt", "r") as file:

    content = file.read()

    print(content)

These examples cover the basics of functions, modules, libraries, and data structures in Python. If you have specific questions or would like more examples on a particular topic, feel free to ask!

Module 6: Object-Oriented Programming (OOP)

6.1 Introduction to OOP Concepts

# oop_concepts.py

# Class Definition

class Car:

    def __init__(self, make, model):

        self.make = make

        self.model = model

    def display_info(self):

        print(f"{self.make} {self.model}")

# Object Creation

my_car = Car("Toyota", "Camry")

my_car.display_info() # Output: Toyota Camry

6.2 Creating and Using Classes and Objects

# classes_and_objects.py

# Inheritance

class ElectricCar(Car):

    def __init__(self, make, model, battery_capacity):

        super().__init__(make, model)

        self.battery_capacity = battery_capacity

    def display_info(self):

        super().display_info()

        print(f"Battery Capacity: {self.battery_capacity} kWh")

# Object Creation

electric_car = ElectricCar("Tesla", "Model S", 75)

electric_car.display_info()

6.3 Inheritance and Polymorphism

# inheritance_and_polymorphism.py

# Polymorphism

def display_vehicle_info(vehicle):

    vehicle.display_info()

# Using Polymorphism

display_vehicle_info(my_car) # Output: Toyota Camry

display_vehicle_info(electric_car) # Output: Tesla Model S, Battery Capacity: 75 kWh

Module 7: Exception Handling

7.1 Understanding and Handling Exceptions

# exception_handling.py

# Handling Exceptions

try:

    result = 10 / 0

except ZeroDivisionError:

    print("Error: Cannot divide by zero.")

7.2 Using Try-Except Blocks Effectively

# try_except_blocks.py

# Custom Exception Handling

class CustomError(Exception):

    pass

try:

    raise CustomError("This is a custom error.")

except CustomError as e:

    print(f"Caught an exception: {e}")

These examples introduce you to the concepts of object-oriented programming and exception handling in Python. If you have specific areas you'd like to explore further or if you have more questions, feel free to let me know!

Module 8: Advanced Topics

    def wrapper():

        print("Before function execution")

        func()

        print("After function execution")

    return wrapper

@decorator

def my_function():

    print("Inside the function")

# Generators

def countdown(n):

    while n > 0:

        yield n

        n -= 1

for num in countdown(5):

    print(num)

8.2 Context Managers

# context_managers.py

# Context Managers (using 'with' statement)

with open("example.txt", "r") as file:

    content = file.read()

    print(content)

8.3 Lambda Functions and map/reduce/filter

# lambda_map_reduce_filter.py

# Lambda Functions

square = lambda x: x**2

# Using map

numbers = [1, 2, 3, 4]

squared_numbers = list(map(square, numbers))

# Using filter

even_numbers = list(filter(lambda x: x % 2 == 0, numbers))

# Using reduce (requires importing from functools)

from functools import reduce

product = reduce(lambda x, y: x * y, numbers)

Module 9: Web Development with Flask (Optional)

9.1 Setting up a Basic Flask Application

@app.route('/')

def home():

    return 'Hello, Flask!'

if __name__ == '__main__':

    app.run(debug=True)

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')

def home():

    return 'About Page'

if __name__ == '__main__':

    app.run(debug=True)
