*Operators in Python* Operators are special symbols or keywords that perform operations on variables and values. *Types of Operators in Python:* *1. Arithmetic Operators* Used for basic math: + (add), - (subtract), * (multiply), / (divide), // (floor divide), % (modulus), ** (power) a = 10 b = 3 print(a + b) # 13 print(a ** b) # 1000 *2. Comparison Operators* Used to compare two values: ==, !=, >, <, >=, <= x = 5 print(x == 5) # True print(x != 3) # True *3. Logical Operators* Used to combine conditional statements: and, or, not age = 20 print(age > 18 and age < 25) # True *4. Assignment Operators* Used to assign values to variables: =, +=, -=, *=, /=, etc. score = 10 score += 5 # score is now 15 *Mini Project: Build a Simple Calculator* Let’s apply what we’ve learned! *Task: Build a calculator that asks the user to enter two numbers and an operator, then prints the result.* *Approach* 1. Take two numbers from the user. 2. Ask for an operator (+, -, *, /). 3. Perform the operation based on what the user entered. 4. Print the result, or shows "Invalid operator!" if the input is wrong. *Python Code*: num1 = float(input("Enter first number: ")) op = input("Enter operator (+, -, *, /): ") num2 = float(input("Enter second number: ")) if op == "+": print(num1 + num2) elif op == "-": print(num1 - num2) elif op == "*": print(num1 * num2) elif op == "/": print(num1 / num2) else: print("Invalid operator!") *React with ❤️ once you’re ready for the quiz*
