"""Boolean values and expressions"""

# a Boolean variable has one of two values:  True or False

type(True)

# when we assign a Boolean value to a variable it becomes
# a Boolean variable

a = False
type(a)

# A boolean expression is an expression that evaluates to a boolean value. 
# The operator == compares two values and produces a boolean value:

5 == 5
5 == 6

# don't confuse the comparison operator == with the assignment operator =

# other comparison operators

x = 1
y = 2

x != y               # x is not equal to y
x > y                # x is greater than y
x < y                # x is less than y
x >= y               # x is greater than or equal to y
x <= y               # x is less than or equal to y

# logical operators:  and, or, not

x = 2
x > 0 and x < 10 
# True if x is greater than 0 and less than 10

x % 2 == 0 or x % 3 == 0 
# True if either of the conditions is true, that is, 
# if the number is divisible by 2 or 3


# not is the negation operator:
not(True)
not(False)
x = 1
y = 2
not(x > y)
