/* A static method does not receive an implicit first argument.

To declare a static method, use this idiom:
|
|
|
|
class C:
|
|
def f(arg1, arg2, ...): ...
|
|
f = staticmethod(f)
|
|
|
|
It can be called either on the class (e.g. C.f()) or on an instance
|
|
(e.g. C().f()); the instance is ignored except for its class.
|

Static methods in Python are similar to those found in Java or C++.

For a more advanced concept, see class methods above.
