I am trying to iterate trough tag attributes with a script:
def main() :
if op is None: return
for tag in op.GetTags() :
bc = tag.GetDataInstance()
for value in bc:
It all goes well until it comes to some "unsupported" attributes, likes of Weight tag, Visual Selector tag...
It gives an error with such tags stating:
"AttributeError: Parameter value not accessible (object unknown in Python)"
I really have no idea how to bypass this. Is there a better way of doing this? Or am I missing something obvious?

That did it, thank you!

The AttributeError stating "Parameter value not accessible (object unknown in Python)" means the Python API doesn't support the data type for the parameter.
So no data value can be given for such parameter.
To bypass this error you can catch and process it like this:
def main() : if op is None: return for tag in op.GetTags() : bc = tag.GetDataInstance() print tag # Loops through parameters dataLen = len(bc) for dataIdx in xrange(dataLen) : dataID = bc.GetIndexId(dataIdx) # Retrieves parameter ID for the given index dataType = bc.GetType(dataID) # Retrieves parameter data type try: data = bc[dataID] # Tries tro get parameter data except AttributeError: print dataID, dataType, "Data not supported" continue # Prints information on parameter data print dataID, dataType, data

That's even more elegant, thank you Yannick!
