# 9.3:  Modify the above function to include an optional argument.  If name=[something], print
# hello, [something]! instead of hello, world!  But if the name= parameter is not passed, revert to
# saying hello, world!

# So your def hello function code will be modified to accept the name=text argument (i.e., def
# hello(name=False)), and then test to see if text has a value -- if it is True (i.e., if name: is
# True).  If it is True, print it after 'hello, '.  If it doesn't, print 'hello, world!'

import yourname

yourname.hello()                # hello, world!
yourname.hello(name='Python')   # hello, Python!
