If I define:
class Bar(object):
@staticmethod
def bar():
# code
pass
class Foo(Bar):
# code
pass
Is it possible for a function call Foo.bar() to determine the class name Foo?

Replace the staticmethod with a classmethod. This will be passed the class when it is called, so you can get the class name from that.
class Bar(object):
@classmethod
def bar(cls):
# code
print cls.__name__
class Foo(Bar):
# code
pass
>>> Bar.bar()
Bar
>>> Foo.bar()
Foo
If you need to find the class information, the appropriate way is to use @classmethod
.
class Bar(object):
@classmethod
def bar(cls):
# code
print(cls.__name__)
class Foo(Bar):
# code
pass
Now your bar
method has a reference to the class as cls
which is the actual class of the caller. And as shown in the code, cls.__name__
is the name of the class you are looking for.
>>> Foo.bar()
Foo
>>> Bar.bar()
Bar
