#The Code below demonstrates the use of the "and" function to supply two arguments to the if statement.
# Parenthesis can be used to separate variables of the statement to make it easier to read, but they are not needed.

# You can also clean up the above code more by using only one equation:
if 16 <= age2 <= 65:
    print("Have a good day at work")

# If statements can also use an "or" function to test between two variables:
# In the code below, "or" is used to test and see if either expression is true. If found true, the if statement
# will print "Enjoy your free time"
if (age2 < 16) or (age2 > 65):

else:
    print("Have a good day at work")

# Python has True and False boolean values, where True is a value of 1, and False is a value of 0
# The Statement below uses the "not" function to print the opposite of the boolean values
print(not False)
print(not True)
# The not function essentially reverses any statement/output.
