import olio

# I WANT TO USE THE MODULE OLIO WHICH HAS MY FUNCTION DEFINITIONS!
# This file that uses functions from the olio module
# won't be able to use the functions from olio unless I import it.

# uncomment below lines to test voting_age()

# These are function calls for olio.voting_age()!
# We store them in variables x and y since the function returns 18 and the variables store whatever the
# function hands back (18) so x and y are assigned the value of the function return (18).
# You can't give arguments if the function definition doesn't have any parameters to provide arguments for!
# Arguments are the values that are passed into our parameters so that the function can start up!

# Using Functions From Module
    # module.function_name( parameters )

# x = olio.voting_age(12)
x = olio.voting_age()
y = olio.voting_age()
z = x + y

print( x )
print( y )
print( z )

print()

# uncomment below lines to test has_blanks()

line1 = input( 'Enter text: ' )
line2 = input( 'Enter text: ' )

# b1 and b2 are assigned the value of what the function returns (True/False!)

b1 = olio.has_blanks( line1 )
b2 = olio.has_blanks( line2 )

# So.. RETURN IS NOT THE SAME THING AS PRINT. This is IMPORTANT!
# print() prints something to the console and return hands something back to the code!
# Just because you return something doesn't mean it's going to get printed!
# We usually store the return value in a variable (b1 = olio.has_blanks(line1)) where the function call
# that returns something is stored in b1 (the return value True/False is stored in b1)
# and THENNN we print b1 and b2 that STORE the return value!
# SO RETURN IS NOT THE SAME THING AS PRINT.

# Usually the function figures something out and then we can display it if we want. We don't always wanna
# print something a function evaluates. More examples on this later!

# These notes are posteddd but go off ig

print( b1 )
print( b2 )

print()

# uncomment below lines to test great_seal()

olio.great_seal()
olio.great_seal()

# So we didn't store these function calls in variables!
# Why?
# Because the function just prints out what we want to see anyways it just EXECUTES the code but doesn't
# hand back anything so we don't want to store it in a variable because then the variable would be assigned to None!
# The function great_seal() returns None by default.

r1 = olio.great_seal()
r2 = olio.great_seal()

# SO IT DOES WHAT'S IN THE FUNCTION aka print butttt the value it returns when we set it to r1 and r2
# is None so that's why r1 and r2 are None.

# ALL FUNCTIONS HAVE A RETURN VALUE (explicit return value or None)
# voting_age() returned 18 so 18 is the RETURN VALUE but great_seal() returns None because we didn't do a return statement.
# The parameters are the things inside the () in a function definition.
# The arguments are the values we pass in for the parameters in the function call.

print( r1 )
print( r2 )

# uncomment below lines to test a_ing()
