Usually, you initialize class variables like that:
class A:
sum = 45
But what is the proper way to initialize class variables if they are the
result of some computation or processing as in the following silly
example (representative for more:
class A:
sum = 0
for i in range(10):
sum += i
The problem is that this makes any auxiliary variables (like "i" in this
silly example) also class variables, which is not desired.
Of course, I could call a function external to the class
def calc_sum(n):
...
class A:
sum = calc_sum(10)
But I wonder whether it is possible to put all this init code into one
class initialization method, something like that:
class A:
@classmethod
def init_class(self):
sum = 0
for i in range(10):
sum += i
self.sum = sum
init_class()
However, this does not work, I get
TypeError: 'classmethod' object is not callable
Is there another way to put an initialization method for the class A
somewhere *inside* the class A?
