Combining Boolean Values with and, or Operators

In this lesson, we will take a closer look at the and and or operators.


and Operator​

The and operator returns true only when all the conditions on both sides are true.

Example of and Operator
is_admin = True

is_logged_in = True

# When the user is an admin and logged in
print(is_admin and is_logged_in)
# True

In the example above, is_admin and is_logged_in returns true only when the user is both an admin (is_admin) and logged in (is_logged_in).

The and operator is used when multiple conditions need to be met simultaneously.


or Operator​

The or operator returns true if at least one of the conditions on either side is true.

Example of or Operator
is_admin = True

has_permission = False

# When the user is either an admin or has permission
print(is_admin or has_permission)
# True

In the example above, is_admin or has_permission returns true when the user is either an admin (is_admin) or has permission (has_permission).

The or operator is used when only one of several conditions needs to be met.


Using and, or Operators Together​

You can combine multiple conditions using and and or operators as follows:

Example of Combining and, or Operators
is_admin = True

is_logged_in = True

has_permission = False

# When the user is an admin and logged in, or has permission
is_allowed = (is_admin and is_logged_in) or has_permission
print(is_allowed)
# True

In the example, the is_allowed variable returns true when is_admin is true and is_logged_in is true, or when has_permission is true.
