I expected this solution:
class Main:

self.value = 0
def count( self ):
self.value += 1
but a student turned in the following solution:
class Main:
value = 0
def count(self):
self.value += 1
I thought that the solution of the student had a shortcoming
but I was not able to put my finger on it. Can you?
Not exactly a shortcoming, but the fact that it works as a solution to
your problem may cause the student to someday write something like:
class Main:
value = []
def add(self, x):
self.value += [x]
and be suprised by the resulting behavior.
