Python Course in 4 to 6 Weeks – Lesson 5: Operators in Python

➕ Python Course in 4 to 6 Weeks – Lesson 5: Operators in Python

Welcome to Lesson 5 of our Python Course in 4 to 6 Weeks! In this lesson, we’ll explore Python operators – the tools that allow you to perform calculations, make comparisons, and add logic to your code.


✅ What You'll Learn

  • Arithmetic Operators ( +, -, *, /, etc. )
  • Comparison Operators ( ==, !=, >, <, etc. )
  • Logical Operators ( and, or, not )
  • Assignment Operators ( =, +=, -=, etc. )
  • Examples and common mistakes

➗ Arithmetic Operators

a = 10
b = 3
print(a + b)  # Addition
print(a - b)  # Subtraction
print(a * b)  # Multiplication
print(a / b)  # Division
print(a % b)  # Modulus (remainder)
print(a ** b) # Exponentiation
print(a // b) # Floor division

🔁 Assignment Operators

Used to assign values to variables and modify them:

x = 5
x += 2  # x = x + 2 → 7
x *= 3  # x = x * 3 → 21
x -= 1  # x = x - 1 → 20

🔍 Comparison Operators

Used to compare values. They return True or False:

a = 5
b = 8
print(a == b)  # False
print(a != b)  # True
print(a > b)   # False
print(a < b)   # True

🧠 Logical Operators

Used to combine multiple conditions:

age = 20
has_ID = True

print(age > 18 and has_ID)  # True
print(age > 18 or has_ID)   # True
print(not has_ID)           # False

⚠️ Common Mistakes

  • ❌ Confusing = (assignment) with == (comparison)
  • ❌ Using quotes with numbers: "5" + 3 → TypeError
  • ❌ Division by zero: 10 / 0 → ZeroDivisionError

🧪 Practice Challenge

Create a Python file named math_game.py that:

  • Asks the user for two numbers
  • Prints the result of all arithmetic operations
  • Compares the numbers and shows which is greater

📥 Tools You'll Need

📌 Final Words

Operators are essential for building logic, performing calculations, and controlling the flow of your programs. With a strong grasp of operators, you're now ready to dive into one of the most powerful tools in programming — conditional statements.
