Phil is right about the function itself, but my guess is that you called GetAttr() on a class instead of an instance. Read up on Python descriptors to understand what difference that makes. https://docs.python.org/3/howto/descriptor.html Basically, you got something like a property object back, but not the value that the property maintaines. If you look up the attribute on the instance, the property (or descriptor) will hand it to you. The same applies to method lookups and other special attributes that may also be implemented as descriptors. Also take a look at Cython, which is designed to keep users from having to learn all these things and instead lets you do them in Python. https://cython.org/ Stefan -- https://mail.python.org/mailman/listinfo/python-list
