Hi,
I got a simple problem regarding so called class variables in Cython. I'm
trying to declare a simple counter as a class variable which is shared
between all instances of that class. The counter's value should be
incremented as instances of the class are created. Cython allows me to
declare a Python dictionary as a class variable, but the following gives me
an error:
# foo.pyx
cdef class Foo:
count = 0
def __cinit__(self):
Foo.count += 1
>>> a = Foo()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "foo.pyx", line 7, in foo.Foo.__cinit__ (foo.c:388)
Foo.count += 1
TypeError: can't set attributes of built-in/extension type 'foo.Foo'
Is there a way to declare an integer class variable in Cython?
