Hi,
I already knew how to define a static method of a class( using
staticmethod() ),
FWIW, it's probably one of the most useless construct in Python IMHO.
classmethod are really much more useful to me.
but I find there isn't a built-in func to build a
static field ( something like staticfield() )
Please define "static field", I just don't understand what it could be.
Now if what you want is a class attribute (ie: an attribute that is
shared by all instances of a class), just declare it at the class level:
class MyClass(object):
shared_attrib = 42
# can be accessed via the class
# or via an instance
MyClass.shared_attrib
m = MyClass()
m.shared_attrib
# but you don't want to rebind it via an instance
m.shared_attrib = 33
m.shared_attrib
MyClass.shared_attrib
# note that the problem is only with rebinding - mutating is ok
class MyOtherClass(object):
shared_attrib = [42]
mo = MyOtherClass()
mo.shared_attrib
mo.shared_attrib.append(33)
mo.shared_attrib
MyOtherClass.shared_attrib
