Python Crash Course: Learn Python Programming from Scratch

Embark on a Python coding journey with this comprehensive crash course. Discover the fundamentals of Python programming, including variables, data types, control flow, functions, and more. Dive into hands-on exercises and practical examples to solidify your understanding and gain the skills to start building Python applications.

Introduction to Python Programming

What is Python?

Python is a powerful, versatile, and beginner-friendly programming language. It is known for its simplicity and readability, making it an ideal choice for beginners and experienced developers alike.

Why Learn Python?

Python is widely used in various domains, including web development, data analysis, artificial intelligence, and automation. Learning Python opens up a world of opportunities and allows you to tackle diverse projects.

Python Basics

Variables and Data Types

Learn how to declare variables and work with different data types in Python, such as strings, numbers, lists, tuples, dictionaries, and booleans. 

# Variable declaration

name = 'John'
age = 25

# Data types

string_variable = 'Hello, World!'
integer_variable = 42
list_variable = [1, 2, 3, 4, 5]
tuple_variable = (1, 2, 3)
dictionary_variable = {'name': 'John', 'age': 25}
boolean_variable = True

Control Flow and Decision Making

Explore control flow statements in Python, such as if-else conditions, loops (for and while), and logical operators. Learn how to make decisions and control the execution flow of your Python programs. 

# if-else condition

if age >= 18:
  print('You are an adult.')
else:
  print('You are a minor.')

# for loop

numbers = [1, 2, 3, 4, 5]
for num in numbers:
  print(num)

# while loop

count = 0
while count < 5:
  print('Count:', count)
  count += 1

Functions and Modularization

Learn how to define and use functions in Python. Understand the concept of modularization and how to break down your code into reusable functions for better organization and maintainability. 

# Function definition

def greet(name):
  print('Hello,', name)

# Function call

greet('John')

Practical Python Projects

Building a Todo List Application

Put your Python skills to the test by building a simple todo list application. Learn how to handle user input, store data, and perform operations such as adding, deleting, and updating tasks. 

# Todo list application

tasks = []

while True:
  print('1. Add task')
  print('2. Delete task')
  print('3. Update task')
  print('4. Exit')
  choice = input('Enter your choice: ')

  if choice == '1':
    task = input('Enter task: ')
    tasks.append(task)
  elif choice == '2':
    task = input('Enter task to delete: ')
    tasks.remove(task)
  elif choice == '3':
    index = int(input('Enter task index: '))
    task = input('Enter new task: ')
    tasks[index] = task
  elif choice == '4':
    break

print('Todo List:', tasks)

Creating a Simple Calculator

Build a basic calculator in Python that can perform arithmetic operations such as addition, subtraction, multiplication, and division. Practice your Python programming skills while creating a useful tool. 

# Calculator

def add(num1, num2):
  return num1 + num2

# Other arithmetic operations

# Subtract, multiply, divide

result = add(5, 3)
print('Result:', result)
