To je zaujimave o dekoratoroch som nic nevedel, Je to az do verzie 2.4?
Predtym (vo verziich pred 2.4) sa to robilo asi takto:
>The question is: How can I implement a static method in python??
You can't.
But, a typical organization is to put one class (or a few closely
related classes) into one file (aka one "module"). Put what you
would have as a static method, as a "global" function in that module
instead. It's not really global; it's in the module's scope, so it's
really just as good as a static method. You can even make it
"private" by starting its name with an underscore (names which start
with an underscore are not normally imported by other modules).
to je teda asi toto
--- module s ---
# module s
def staticM(pp):
print pp*2
class s(object):
def M(pp):
print pp*2
--- koniec modulu ---
--- program ---
import s;
s.staticM("nazdar ")
--- koniec programu ---
