[Tutor] static methods and class methods

[Christopher Spears]

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!
