Python Logical Operators

Python logical operators

Created By: chatGPT

In Python, logical operators are used to combine multiple conditional statements. The three main logical operators are AND, OR, and NOT. These operators help in evaluating expressions to provide a final Boolean result, which can be either True or False. Let's dive into each one with examples.

a = True
b = False

# AND operator
result_and = a and b  # This will be False because not all operands are True

# OR operator
result_or = a or b  # This will be True because at least one operand is True

# NOT operator
result_not = not a  # This will be False because we negate the True value

The AND operator returns True only if both operands are True. If either operand is False, it returns False. This is useful when you want to ensure that multiple conditions are met.

x = 5

if x > 0 and x < 10:
    print('x is between 0 and 10')  # This will print because both conditions are True

The OR operator returns True if at least one of the operands is True. If both are False, only then does it return False. You can use this when you want to check if at least one condition fulfills your requirement.

y = 15

if y < 10 or y > 20:
    print('y is either less than 10 or greater than 20')  # This will not print since both conditions are False

The NOT operator is used to reverse the Boolean value of the operand. If the operand is True, applying NOT will make it False, and vice versa. It's useful for scenarios where you want to negate a condition.

flag = True

if not flag:
    print('Flag is False')  # This won't print because flag is True

You can also combine these logical operators to create more complex conditions. When combining these, be sure to consider operator precedence: not operators are evaluated first, followed by and, and finally or.

num = 8

if num > 5 and not (num == 10 or num == 12):
    print('Num is greater than 5 and not 10 or 12')  # This will print
