1️⃣ Arithmetic Operators

Example 1: Basic Calculations

a = 10
b = 3

print(a + b)
print(a - b)
print(a * b)
print(a / b)
print(a % b)
print(a ** b)

Output

13
7
30
3.3333333333333335
1
1000

Explanation

• + adds values
• - subtracts
• * multiplies
• / divides (always gives float)
• % gives remainder
• ** is power

---

Example 2: Salary Calculation

salary = 30000
bonus = 5000

total_salary = salary + bonus
print("Total Salary:", total_salary)

Output

Total Salary: 35000

---

2️⃣ Assignment Operators

Example

salary = 20000
salary += 5000
salary -= 2000

print(salary)

Output

23000

Explanation

• += adds and stores
• -= subtracts and stores

---

3️⃣ Comparison (Relational) Operators

Example

age = 25

print(age > 18)
print(age < 18)
print(age == 25)
print(age != 30)

Output

True
False
True
True

Explanation

• > greater than
• < less than
• == equal to
• != not equal to

---

Example with Names

name1 = "Sameer"
name2 = "Ayesha"

print(name1 == name2)

Output

False

---

4️⃣ Logical Operators

Example

age = 22
has_id = True

print(age >= 18 and has_id)
print(age < 18 or has_id)
print(not has_id)

Output

True
True
False

Explanation

• and → both conditions must be true
• or → any one condition true
• not → reverses result

---

5️⃣ Identity Operators (is, is not)

Example

a = 10
b = 10

print(a is b)
print(a is not b)

Output

True
False

Explanation
Checks if both variables refer to the same object

---

6️⃣ Membership Operators (in, not in)

Example

students = ["Sameer", "Ayesha", "Saddam"]

print("Sameer" in students)
print("Chandini" in students)

Output

True
False

---

7️⃣ Operator Precedence

Example

result = 10 + 5 * 2
print(result)

Output

20

Explanation

• Multiplication happens first → 5 * 2 = 10
• Then addition → 10 + 10 = 20

---

Example with Brackets

result = (10 + 5) * 2
print(result)

Output

30

---

8️⃣ Expressions Using Variables

Example

name = "Gousya"
age = 20

message = name + " is " + str(age) + " years old"
print(message)

Output

Gousya is 20 years old

---

9️⃣ Input + Operators

marks1 = int(input("Enter marks 1: "))
marks2 = int(input("Enter marks 2: "))

total = marks1 + marks2
average = total / 2

print("Total:", total)
print("Average:", average)

Sample Output

Enter marks 1: 80
Enter marks 2: 90
Total: 170
Average: 85.0

---

🔟 Real-Life Mini Example

salary = 25000
expenses = 18000

savings = salary - expenses
print("Savings:", savings)

Output

Savings: 7000
