📘 What is Python?

Python is a powerful, beginner-friendly programming language used in web development, data science, artificial intelligence, automation, and more.

Why Learn Python?

• ✅ Simple and readable syntax
• ✅ Huge community and support
• ✅ Can run on mobile using apps like Pydroid 3
• ✅ Used by big companies like Google, Netflix, and Facebook

🧠 Python Basics (Days 1–7)

Here you will learn the foundational concepts of Python programming.

📌 Variables & Data Types

Variables are used to store data. Python is dynamically typed, so you don't need to declare the type.

x = 10  # integer
y = 3.14  # float
name = "John"  # string
is_active = True  # boolean
  

Explanation:

• x stores an integer value.
• y stores a float (decimal number).
• name stores a string (text).
• is_active stores a boolean (True/False).

📌 Conditional Statements

Use if, elif, and else to make decisions in your program.

x = 20
if x > 10:
    print("x is greater than 10")
elif x == 10:
    print("x is 10")
else:
    print("x is less than 10")
  

Explanation: The code checks the value of x and prints a message based on its condition.

📌 Loops

Loops allow you to run a block of code multiple times.

# for loop
for i in range(5):
    print(i)while loop

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

Explanation: The for loop runs 5 times and prints 0 to 4. The while loop does the same using a condition.

📌 Functions

Functions let you reuse blocks of code.

def greet(name):
    print("Hello, " + name)greet("Alice") 

Explanation: The function greet() takes a parameter name and prints a greeting.

⚙️ Intermediate Concepts (Days 8–15)

📌 Lists, Tuples & Dictionaries

my_list = [1, 2, 3]
my_tuple = (4, 5, 6)
my_dict = {"name": "John", "age": 30}
  

Explanation: Lists are mutable, tuples are immutable, and dictionaries store key-value pairs.

📌 String Manipulation

message = "Hello World"
print(message.lower())
print(message.replace("World", "Python"))
  

Explanation: Convert string to lowercase and replace part of a string.

📌 File Handling

with open("sample.txt", "w") as file:
    file.write("Hello File")
  

Explanation: This creates or overwrites a file and writes text to it.

🔧 Advanced Topics (Days 16–30)

• Object-Oriented Programming (OOP)
• Modules & Packages
• Error Handling (try-except)
• Working with APIs (requests)
• Using External Libraries (e.g., pandas, numpy)

class Dog:
    def __init__(self, name):
        self.name = name

    def bark(self):
        print(self.name + " says woof!")

my_dog = Dog("Tommy")
my_dog.bark()
  

Explanation: This is an example of Object-Oriented Programming. The class Dog has a method bark().
