Dear sirs,
I am only begining Python and this problem has confused me for long.
question: How do I upcall parents methods? I mean,

class p:
def m(self):
print "This is parent method"
class c(p):
def m(self):
# I want to override m by first calling p.m and print something else

how do I write c.m()??
thanks
