 ## Practice Questions and Resources
 
+### 🭝 Python Operations - Practice Questions
+
+This document contains practice questions to help you strengthen your understanding of **Python operators**, including:
+
+- Arithmetic Operators (`+`, `-`, `*`, `/`, `//`, `%`, `**`)
+- Comparison Operators (`==`, `!=`, `>`, `<`, `>=`, `<=`)
+- Logical Operators (`and`, `or`, `not`)
+- Assignment Operators (`=`, `+=`, `-=`, etc.)
+- Bitwise Operators (`&`, `|`, `^`, `~`, `<<`, `>>`)
+
+---
+
+## ✅ Arithmetic Operators
+
+1. Write a program that takes two numbers from the user and displays the result of all arithmetic operations.
+2. Calculate the area and perimeter of a rectangle using arithmetic operators.
+3. Find the square root and cube of a number using `**`.
+4. Convert total seconds into hours, minutes, and seconds using `//` and `%`.
+
+---
+
+## ✅ Comparison (Relational) Operators
+
+1. Write a program to compare two numbers and print which one is greater.
+2. Check if a person is eligible to vote (age >= 18).
+3. Take input from the user and check if it is a positive, negative, or zero.
+4. Compare the lengths of two strings and print if they are equal.
+
+---
+
+## ✅ Logical Operators
+
+1. Check if a number is between 1 and 100 (inclusive).
+2. Write a program to check if a year is a leap year using logical conditions.
+3. Take three subject marks from the user and check if the student has passed all subjects (passing marks >= 40).
+4. Ask the user if they are "registered" and "logged in". Allow access only if both conditions are true.
+
+---
+
+## ✅ Assignment Operators
+
+1. Take a number and update its value using `+=`, `-=`, `*=`, `/=`, etc.
+2. Write a calculator that performs operations and updates the value step by step using assignment operators.
+3. Create a counter that starts at 0 and increments/decrements based on user input.
+
+---
+
+## ✅ Bitwise Operators
+
+1. Perform bitwise AND, OR, XOR between two integers and print the result.
+2. Show how left shift (`<<`) and right shift (`>>`) work with an example.
+3. Write a program that checks if a given number is even or odd using bitwise AND.
+4. Take two numbers and perform all bitwise operations on them.
+
+---
+
+## 💡 Bonus Challenges
+
+1. Simulate a simple login system using logical operators.
+2. Write a program to swap two numbers without using a third variable (hint: use arithmetic or bitwise operators).
+3. Use all types of operators in a single program that acts like a mini calculator.
