Correct Answer: B) 3

📘Explanation:

In Python, // is the floor division operator in Python.
It divides the numbers and returns the integer part (floor value).
So 10 // 3 gives 3, not 3.33.

✅ Correct Answer: B) False

🧠 Explanation :

5 > 3 → True

2 < 1 → False

True and False → False

📌 Rule: and returns True only if both conditions are True.

🐍 PYTHON – DAY 1 STUDY MATERIAL
✨ Topic: Introduction to Python & Installation

━━━━━━━━━━━━━━━━━━━

📌 What is Python?

Python is a high-level, interpreted, and general-purpose programming language.
It is easy to learn and widely used in web development, data science, artificial intelligence, automation, and scripting.

━━━━━━━━━━━━━━━━━━━

🎯 Why Learn Python?

✅ Easy to read and write
✅ Beginner-friendly syntax
✅ Huge library support
✅ Platform independent
✅ Used by top companies like Google, Netflix, Instagram

━━━━━━━━━━━━━━━━━━━

⚙️ Features of Python

✔ Interpreted Language
✔ High-Level Language
✔ Object-Oriented
✔ Dynamically Typed
✔ Portable (Windows, Linux, Mac)
✔ Open Source and Free

━━━━━━━━━━━━━━━━━━━

🔢 Python Versions

❌ Python 2 – Deprecated
✅ Python 3 – Recommended
👉 Always use Python 3

━━━━━━━━━━━━━━━━━━━

💻 How to Install Python (Windows)

1️⃣ Visit 👉 https://www.python.org
2️⃣ Download Python 3.x
3️⃣ Select ☑ Add Python to PATH
4️⃣ Click Install
5️⃣ Verify installation using:
python --version

━━━━━━━━━━━━━━━━━━━

🚀 Python Execution Modes

🔹 Interactive Mode
print("Hello Python")

🔹 Script Mode
Create file: hello.py
print("Hello Python")

Run using command:
python hello.py

━━━━━━━━━━━━━━━━━━━

👋 First Python Program

print("Hello World")

🖨 Output:
Hello World

━━━━━━━━━━━━━━━━━━━

🧠 Python Syntax Rules

• Python is case-sensitive
• Indentation is mandatory
• No semicolon required

Example:

if True:
print("Python is easy")

━━━━━━━━━━━━━━━━━━━

💬 Comments in Python

🔹 Single-line comment
This is a comment

🔹 Multi-line comment
"""
This is
a multi-line
comment
"""
━━━━━━━━━━━━━━━━━━━

📝 Practice Tasks – Day 1

✔ Install Python
✔ Run Python in interactive mode
✔ Write your first Python program
✔ Print your name using Python

Example:
print("My name is Soham")

━━━━━━━━━━━━━━━━━━━

🎯 Day 1 Goal

✔ Understand Python basics
✔ Install Python successfully
✔ Run your first Python program

━━━━━━━━━━━━━━━━━━━

🐍 PYTHON – DAY 2 STUDY MATERIAL
✨ Topic: Variables & Data Types

━━━━━━━━━━━━━━━━━━━

📌 What is a Variable?
A variable is a name given to a memory location used to store data in a program.
Python variables do not need data type declaration.

Example:
x = 10
name = "Python"

━━━━━━━━━━━━━━━━━━━

🧠 Rules for Naming Variables

✔ Must start with a letter (a–z, A–Z) or underscore (_)
✔ Can contain letters, numbers, and underscore
❌ Cannot start with a number
❌ Cannot use keywords

Valid:
my_var, _count, total1

Invalid:
1total, my-var, class

━━━━━━━━━━━━━━━━━━━

⚙️ Dynamic Typing in Python

Python automatically decides the data type based on the value.

Example:
x = 10
x = "Hello"

Same variable, different data type ✔

━━━━━━━━━━━━━━━━━━━

🔢 Data Types in Python

📍 Integer (int)
Stores whole numbers
Example:
a = 25

📍 Float (float)
Stores decimal numbers
Example:
b = 10.5

📍 String (str)
Stores text or characters
Example:
name = "Python"

📍 Boolean (bool)
Stores True or False
Example:
is_active = True

━━━━━━━━━━━━━━━━━━━

🔍 Check Data Type

Use type() function

Example:
x = 10
print(type(x))

Output:
<class 'int'>

━━━━━━━━━━━━━━━━━━━

🔁 Type Conversion (Type Casting)

📌 Convert to Integer
int(10.5) → 10

📌 Convert to Float
float(5) → 5.0

📌 Convert to String
str(100) → "100"

Example:
x = int("20")
y = float(5)

━━━━━━━━━━━━━━━━━━

📥 User Input in Python

Python takes input as string by default.

Example:
name = input("Enter your name: ")
print(name)
Input with type conversion:
age = int(input("Enter age: "))

━━━━━━━━━━━━━━━━━━━

🧮 Multiple Assignment

Example:
a, b, c = 10, 20, 30
Same value assignment:
x = y = z = 5

━━━━━━━━━━━━━━━━━━━

📝 Practice Tasks – Day 2

✔ Create variables of different data types
✔ Use type() to check data type
✔ Take user input for name and age
✔ Convert string input to integer

Example Program:
name = input("Enter name: ")
age = int(input("Enter age: "))
print(name, age)

━━━━━━━━━━━━━━━━━━━

🎯 Day 2 Goal

✔ Understand variables
✔ Learn Python data types
✔ Take user input confidently
