Hi,
Without knowing what code caused this error, it's a bit difficult to
specifically diagnose, but it seems that you might be trying to override an
existing method? The doc string gives some details as to the function that
is throwing this error:
def *monkey_patch*(name, bases, namespace):
"""A 'metaclass' for adding new methods to an existing class.
In this version, existing methods can't be overridden; this is by
design, to avoid accidents.
Usage example:
class PatchClass(TargetClass):
__metaclass__ = monkey_patch
def foo(self, ...): ...
def bar(self, ...): ...
This is equivalent to:
def foo(self, ...): ...
def bar(self, ...): ...
TargetClass.foo = foo
TargetClass.bar = bar
PatchClass = TargetClass
Note that PatchClass becomes an alias for TargetClass; by convention
it is recommended to give PatchClass the same name as TargetClass.
