There's something funny there. How does each Quark know what its color
and mass is? What is the definition of getcolor and getmass? A more
common solution is:
class Quark:
def __init__(self, color, mass):
self.color=color
self.mass=mass
But I guess you've already got this part working....

You aren't changing the list. You're just reading from it, never writing
to it. Here's a straightforward way to do it:
flavornames = ['up', 'down', 'strange', 'charm', 'top', 'bottom']
flavors = []
for each in flavornames:
flavors.append(Quark())
for each in flavors:
print each.color
I still don't know where to get the colors or masses. Also, don't you
want to somehow associate the flavornames with the quarks you create?
