I have two possible values for Z_block in the block code i.e disk_object.data.data.di_data[0] or block.data.data.di_data.data[0][0]
def get_block(): ''' Get Z block '' if block.data.data.di_data.data[0][0] is not None: Z_block = block.data.data.di_data.data[0][0] else: Z_block = disk_object.data.data.di_data[0] if not Z_block: return False return Z_block I have a problem with if and else satement i.e if IF codition fails the code would exit with "AttributeError: 'list' object has no attribute 'data' " error Any suggestion on how this can be handled better , Will ignoring the exceptions in try -except with pass be good or are there easier ways ) , try: Z_block = block.data.data.di_data.data[0][0]except AttributeError as e: pass I am a Linux user on Python 2.7 Regards, Ganesh -- https://mail.python.org/mailman/listinfo/python-list
