+
+Welcome! This track covers Python fundamentals and popular libraries.
+## What is Python ?
+Python is one of the most popular programming languages. It’s simple to use, packed with features and supported by a wide range of libraries and frameworks. Its clean syntax makes it beginner-friendly. It's
+
+- A high-level language, used in web development, data science, automation, AI and more.
+- Known for its readability, which means code is easier to write, understand and maintain.
+- Backed by library support, so we don’t have to build everything from scratch, there’s probably a library that already does what we need.
+
+## Why to Learn Python?
+- Requires fewer lines of code compared to other programming languages.
+- Provides Libraries / Frameworks like Django, Flask, Pandas, Tensorflow, Scikit-learn and many more for Web - 
+- Development, AI/ML, Data Science and Data Analysis
+- Cross-platform, works on Windows, Mac and Linux without major changes.
+- Used by top tech companies like Google, Netflix and NASA.
+- Many Python coding job opportunities in Software Development, Data Science and AI/ML.
+
+## Get Started with Python
+Install Python in your system. 
+
+
+**What you’ll learn**
+- Syntax & variables
+- Data types and data structures
+- Functions & modules
+- Virtual environments and pip
+- NumPy & pandas basics
+
+> Tip: You can run most examples in a REPL: `python` or `python3` in your terminal.

+# Variables and Syntax in Python
+
+We'll learn the syntax and variables used in Python.
+
+---
+
+##  Printing in Python
+Python has a very simple and clean syntax, which makes it beginner-friendly.
+```python
+print("Hello, World!")
+```
+Thus prints - Hello, World!
+Input and Output : 
+```python
+name = input("Enter your name: ")
+print("Hello,", name, "! Welcome!") 
+#Enter your name: Rohan
+#Hello, Rohan"! Welcome!
+```
+
+##  Variables
+In Python, we assign variables some value. 
+Below are a few examples.
+```python
+x = 10           # int
+pi = 3.14        # float
+name = "Zarine"  # str
+is_ok = True     # bool
+```
+💡 In Python, variables are case-sensitive (Name and name are different).
+
+##  Multiple Assignment
+This is how we assign multiple variables at the same time!
+```python
+
+a, b, c = 1, 2, 3
+x = y = z = 0   # all assigned to 0
+```
+##  Naming Rules
+There are some rules to be followed while naming a variable.
+- Can contain letters, numbers, and underscores.
+- Cannot start with a number.
+- Keywords like for, if, while cannot be used as variable names.
+
+Valid examples:
+
+```python
+
+user_name = "Alice"
+marks1 = 90
+_total = 100
+```
+Invalid:
+
+```python
+
+1value = 5       # ❌ cannot start with number
+for = 10         # ❌ cannot use keyword
+```
+##  Comments
+Single line:
+
+```python
+
+# This is a comment
+```
+Multi-line (docstring style):
+
+```python
+
+"""
+This is a 
+multi-line comment
+"""
+```
+## 📝 Quick Exercise
+Create three variables: age, pi, student_name. Assign appropriate values and print them.

+title: Data Structures
+sidebar_position: 3
+---
+
+# Data Structures in Python
+
+Python comes with built-in data structures that make it powerful and easy to use.
+
+---
+
+##  Lists
+- Ordered, mutable (can be changed), allow duplicates.
+
+```python
+fruits = ["apple", "banana", "cherry"]
+print(fruits[0])     # apple
+fruits.append("mango")
+print(fruits)        # ['apple', 'banana', 'cherry', 'mango']
+```
+##  Tuples
+
+Ordered, immutable, allow duplicates.
+```python
+point = (10, 20)
+print(point[1])    # 20
+```
+
+##  Sets
+
+Unordered, unique elements, no duplicates.
+```python
+tags = {"python", "ml", "ece", "python"}
+print(tags)   # {'ece', 'ml', 'python'}
+```
+
+##  Dictionaries
+
+Key-value pairs, unordered (insertion-ordered since Python 3.7).
+```python
+student = {"name": "Rohan", "year": 2, "branch": "ECE"}
+print(student["name"])     # Rohan
+student["year"] = 3
+print(student)             # {'name': 'Rohan', 'year': 3, 'branch': 'ECE'}
+```
+
+## 📝 Quick Exercises
+
+- Create a list of your 5 favorite movies and print the 2nd one.
+- Make a dictionary with your details (name, age, college). Print the age.
+- Try to add a duplicate element to a set and see what happens.

+title: Functions
+sidebar_position: 4

+
+# Functions in Python
+
+Functions let you organize code into reusable blocks.
+
+---
+
+##  Defining a Function
+We define a function in Python with the use of def(). Below is an example.
+```python
+def greet():
+    print("Hello, welcome to Python!")
+
+greet()
+```
+## Parameters and Arguments
+We pass parameters and arguments through functions like in the example below. 
+```python
+def add(a, b):
+    return a + b
+
+result = add(10, 5)
+print(result)   # 15
+```
+## Default Parameters
+```python
+def greet_user(name="Guest"):
+    print(f"Hello, {name}!")
+
+greet_user()         # Hello, Guest!
+greet_user("Zarine") # Hello, Zarine!
+```
+
+## Keyword Arguments
+```python
+def student_info(name, branch, year):
+    print(f"{name} studies {branch} in year {year}")
+
+student_info(branch="ECE", year=2, name="Zarine")
+```
+## Variable Arguments (*args, **kwargs)
+```python
+def add_all(*nums):
+    return sum(nums)
+
+print(add_all(1, 2, 3, 4))  # 10
+```
+
+## Lambda Functions
+
+```python
+square = lambda x: x * x
+print(square(5))   # 25
+```
+
+## 📝 Quick Exercises
+- Write a function multiply(x, y) that returns the product.
+- Write a function is_even(num) that prints "Even" or "Odd".
+- Create a lambda function that reverses a string.

+
+# Projects with Python Basics
+
+Now that you know **variables, data structures, and functions**, let’s build some small projects.
+
+---
+
+##  1. Calculator
+Uses **variables + functions**.
+
+```python
+def add(a, b): return a + b
+def sub(a, b): return a - b
+def mul(a, b): return a * b
+def div(a, b): return a / b
+
+a = int(input("Enter first number: "))
+b = int(input("Enter second number: "))
+
+print("Addition:", add(a, b))
+print("Subtraction:", sub(a, b))
+print("Multiplication:", mul(a, b))
+print("Division:", div(a, b))
+```
+## 2. Student Information Manager
+
+Uses dictionaries + functions.
+```python
+
+def add_student(name, branch, year):
+    return {"name": name, "branch": branch, "year": year}
+
+student1 = add_student("Zarine", "ECE", 2)
+print(student1)
+```
+
+## 3. To-Do List App
+
+Uses lists + loops.
+```python
+
+tasks = []
+
+def add_task(task):
+    tasks.append(task)
+
+def show_tasks():
+    print("Your Tasks:")
+    for i, t in enumerate(tasks, 1):
+        print(f"{i}. {t}")
+
+add_task("Study Python")
+add_task("Complete Assignment")
+show_tasks()
+```
+## 4. Word Counter
+
+Uses strings + functions.
+```python
+def word_count(text):
+    words = text.split()
+    return len(words)
+
+sentence = "Python makes programming fun"
+print("Word count:", word_count(sentence))
+```
+
+## 5. Guess the Number Game
+
+Uses loops + conditions + random module.
+```python
+import random
+
+secret = random.randint(1, 10)
+guess = int(input("Guess a number (1-10): "))
+
+if guess == secret:
+    print("🎉 Correct!")
+else:
+    print("❌ Wrong! The number was", secret)
+```
+
+## 📝 Mini Challenges for You
+
+- Extend the Calculator to handle exponentiation (a ** b).
+- Add a "remove task" option in the To-Do List App.
+- Modify Word Counter to also count characters.
+- Make Guess the Number keep running until the user guesses correctly.
