How to Combine Conditions in Python
In Boolean logic, or and and are fundamental operators. The or operator returns True if at least one condition is true, while the and operator returns True only if all conditions are true. Use lowercase and and or to combine conditions effectively.
123456789# Check if a person has a valid membership and a reservation has_membership = True has_reservation = False # Both conditions must be true for access (AND) print(has_membership and has_reservation) # At least one condition must be true for access (OR) print(has_membership or has_reservation)
You can combine multiple conditions using these operators. When combining complex expressions, use parentheses to clearly define the order of operations. This ensures that your logic is evaluated correctly and avoids unexpected results.
1234567# Check if a person has a valid membership, a reservation, or VIP status has_membership = True has_reservation = False is_vip = True # Chained condition with parentheses to change precedence print(has_membership and (has_reservation or is_vip))
The not operator is used to invert a boolean value. It changes True to False and False to True. This is useful when you need to negate a condition or check the opposite of a given value.
12345678# Check if something is available available = True # The availability status print(available) # Use the 'not' operator to invert the availability status print(not available)
