Logical Operators

Logical Operators in Python are used to combine multiple conditions and return a result as True or False.

Real-Life Example

Logical operators are like decisions in real life:

• If you have a ticket AND ID → you can enter
• If you have money OR card → you can pay
• If it is NOT raining → you can go outside

Explanation

These operators help in decision-making by checking more than one condition at the same time.

They are commonly used in:

• if statements
• Loops
• Real-life problem solving

They always return a Boolean value (True/False).

Types of Logical Operators

• and → Returns True if both conditions are True
• or → Returns True if at least one condition is True
• not → Reverses the result (True → False, False → True)

Example Program 1

a = 10

print(a > 5 and a < 20)
print(a > 15 or a < 20)
print(not(a > 5))

Output:

True
True
False

Example Program 2

age = 18
has_id = True

if age >= 18 and has_id:
    print("Eligible to vote")
else:
    print("Not eligible")

Output:

Eligible to vote

Explanation

• age >= 18 → checks if the person is 18 or older
• has_id → checks if the person has an ID proof
• and → both conditions must be True

Common Beginner Mistakes

•  Confusing and / or
•  Forgetting brackets
•  Misunderstanding True/False
•  Wrong condition combinations
  
  

Key Points 

• Logical operators combine conditions
• They return True or False
• Used in decision-making programs
• Important for building logic in Python
  
  

Tips 

• Use and when both conditions must be true
• Use or when at least one condition is enough
• Use not to reverse results
• Practice using if conditions
