7. Python Operators Explained with Examples

Operators in Python are special symbols used to perform operations on variables and values. Whether you are performing calculations, comparing values, or building logical conditions, operators are essential in every Python program.

Core Idea: Operators tell Python what action to perform between values.

1) Arithmetic Operators

Arithmetic operators are used to perform mathematical operations.

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)  # Power (exponent)
print(a // b)  # Floor division

Floor division (//) removes decimals and returns the integer part.

2) Comparison Operators

Comparison operators compare two values and return True or False.

x = 5
y = 10

print(x == y)   # Equal
print(x != y)   # Not equal
print(x > y)    # Greater than
print(x < y)    # Less than
print(x >= y)   # Greater or equal
print(x <= y)   # Less or equal

Comparison operators are mostly used inside conditions (if statements).

3) Logical Operators

Logical operators combine multiple conditions.

age = 20
is_student = True

print(age > 18 and is_student)
print(age > 25 or is_student)
print(not is_student)

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

4) Assignment Operators

Assignment operators assign values to variables.

number = 5

number += 2   # number = number + 2
number -= 1   # number = number - 1
number *= 3
number /= 2

Compound assignment makes code shorter and cleaner.

5) Membership Operators

Membership operators check if a value exists in a sequence.

fruits = ["apple", "banana", "orange"]

print("apple" in fruits)
print("grape" not in fruits)

6) Identity Operators

Identity operators compare memory locations (not just values).

a = [1, 2, 3]
b = a
c = [1, 2, 3]

print(a is b)     # True
print(a is c)     # False
print(a == c)     # True

is checks identity (same object), while == checks value equality.

7) Bitwise Operators (Advanced)

Bitwise operators work at the binary level. These are more advanced but useful in low-level programming.

a = 5    # 0101
b = 3    # 0011

print(a & b)  # AND
print(a | b)  # OR
print(a ^ b)  # XOR
print(~a)     # NOT
print(a << 1) # Left shift
print(a >> 1) # Right shift

8) Operator Precedence

Python follows an order of operations similar to mathematics. For example:

result = 2 + 3 * 4
print(result)  # 14, not 20

Use parentheses to control priority:

result = (2 + 3) * 4
print(result)  # 20

Parentheses make your code clearer and safer.

Conclusion

Operators are the building blocks of logic and computation in Python. From arithmetic calculations to complex logical conditions, understanding operators helps you write cleaner and more powerful programs.

Practice combining different operators inside conditions and loops. Mastery of operators makes problem-solving much easier.
