''' Purpose: Exercise module olio
'''

import olio   # get the olio module by importing it to use functions in olio

# uncomment below lines to test voting_age()
# from the module olio, get the function voting_age()
# voting_age() does not have any parameters so when we invoke it, we don't need to pass in an argument
#   will always hand back (return) 18 because we defined it that way
x = olio.voting_age()
y = olio.voting_age()

print( x )

b2 = olio.has_blanks( line2 )

print( b1 )
print( b2 )

# uncomment below lines to test great_seal()
# since function great_seal() doesn't return, we can just invoke it without assigning it to a variable
# since great_seal() prints something, the result will show up in the console

# we didn't define what to return in a_ing() so python defaults to None
# a_ing() also print stuff so when we invoke it, the print statement will print
# the result from the function out.

print()

# a_ing() does not return anything, but it defaults to None
# if we assign the return value to a variable, then print it out
# that variable will hold None
result = olio.a_ing( nbr3 )    # result will hold None so when we print it out, we see None
print( result )
