The error message is: "UnboundLocalError: local variable 'start'
referenced before assignment". The same thing happens if I omit start
and just use start_num directly.
How can I do it in Python?
Since no one has suggested it:
class make_counter(object):
def __init__(self, i):
self.i = i
def __call__(self):
i = self.i
self.i += 1
return i
