>>valedictori an = max((student.gp a, student.name) for student in

graduates)

NOTE: page and graduates are not defined and this won't run without them.
I defined them like so to make this work:

page = ("The quick brown","fox jumped over","the lazy dog's","back 123
times." )

class Graduate:
def __init__(self, name, gpa):
self.name = name
self.gpa = gpa
gpa = 0
name = ""

graduates = (Graduate("Char lie Brown",8.09), Graduate("Snoop y",3.7),
Graduate("Lucy Brown",3.5))

Bugs and other problems should be reported in bugs.python.org

Otherwise they will probably get lost.

Next time, please also add a URL that is usable for a larger group of people
than those that have access to your C: drive.

I defined them like so to make this work:

Correctly seen. Report at bugs.python.org !

page = ("The quick brown","fox jumped over","the lazy dog's","back 123
times." )

class Graduate:

Always derive new classes from object as in

class Graduate(object ):

def __init__(self, name, gpa):
self.name = name
self.gpa = gpa

and indentation is normally 4 spaces, at least in public Python documentation.

gpa = 0
name = ""

Why do you introduce two class variables with the same name?
(not useful, you can delete them)
