hello,
I'm learning Python and OOP, and I am confronted with a rather
theoretical problem.
If I run the following script:
class stepper:
def __getitem__(self, i):
return self.data[i]
X=stepper()
X.data="Spam"
for item in X:
print item,
... what I get is S p a m which seems logical to me since the
loop stops after the 4th character.
However if I run
class stepper:
def __getitem__(self, i):
return i
X=stepper()
X.data="Spam"
for item in X:
print item,
... what I get is an endless loop, starting at zero: 0 1 2 3 4 5 6
7 8 9 10 11 and so on.
My question is: why does this second script not stop after printing
number 3? what made the first one stop while the second one will not?
Thanks for your advise
Vicente Soler
