I am reading Wesley Chun's "Core Python Programming" (2nd Edition) and have
reached the part on static and class methods. I typed in the following to
demonstrate the difference between the two methods:
>>> class TestClassMethod:
... def foo(cls):
... print 'calling class method foo()'
... print 'foo() is part of class:',cls.__name__
... foo = classmethod(foo)
...
>>> class TestStaticMethod:
... def foo():
... print 'calling static method foo()'
... foo = staticmethod(foo)
...
>>> tsm = TestStaticMethod()
>>> TestStaticMethod.foo()
calling static method foo()
>>> tcm = TestClassMethod()
>>> TestClassMethod.foo()
calling class method foo()
foo() is part of class: TestClassMethod
>>> tcm.foo
<bound method classobj.foo of <class __main__.TestClassMethod at 0xb7da0f2c>>
>>>
According to the author, the result for typing in 'tcm.foo' is
calling class method foo()
foo() is part of class: TestClassMethod
Did I do something wrong or is this an error on the book's part? Intuitively,
the answer I received makes more sense to me. I am still unsure of the
difference of static and class methods. Can someone enlighten me?
Thanks!
