Python Operators

What are Operators?

Operators are special symbols used to perform operations on values and variables.

1. Arithmetic Operators

Arithmetic operators are used to perform mathematical calculations.

+   Addition
-   Subtraction
*   Multiplication
/   Division
%   Modulus
//  Floor Division
**  Exponentiation

Example

a = 10
b = 3

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

2. Comparison Operators

Comparison operators compare two values. They return either True or False.

==   Equal to
!=   Not equal to
>    Greater than
<    Less than
>=   Greater than or equal to
<=   Less than or equal to

Example

a = 10
b = 5

print(a == b)
print(a != b)
print(a > b)
print(a < b)
print(a >= b)
print(a <= b)

False
True

True
False

3. Assignment Operators

Assignment operators are used to assign or update values in variables.

=    Assign
+=   Add and assign
-=   Subtract and assign
*=   Multiply and assign
/=   Divide and assign

Example

x = 10

x += 5
print(x)

x -= 3
print(x)

x *= 2
print(x)

4. Logical Operators

Logical operators are used to combine multiple conditions.

and    True if both conditions are True
or     True if at least one condition is True
not    Reverses the result

Example

age = 20

print(age >= 18 and age <= 60)
print(age < 18 or age > 60)
print(not(age >= 18))

True
False
False

5. Practical Example

Operators can be used together to solve real programming problems.

math = 80
python = 90
dsa = 85

total = math + python + dsa
average = total / 3

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

Total = 255
Average = 85.0
