after checking reason of error so I found paython is not recalling specific state such as when I ran code : IN [ ] df_inputs_prepr['addr_state'] OUT [ ] 427211 SC 206088 NJ 136020 GA 412305 MA 36159 CA Name: addr_state, Length: 373028, dtype: object But when I apply code: IN [ ] df_inputs_prepr['addr_state:SC'] OUT [ ] --------------------------------------------------------------------------- KeyError Traceback (most recent call last) ~\anaconda3\lib\site-packages\pandas\core\indexes\base.py in get_loc(self, key, method, tolerance) 2897 try: -> 2898 return self._engine.get_loc(casted_key) 2899 except KeyError as err: pandas\_libs\index.pyx in pandas._libs.index.IndexEngine.get_loc() pandas\_libs\index.pyx in pandas._libs.index.IndexEngine.get_loc() pandas\_libs\hashtable_class_helper.pxi in pandas._libs.hashtable.PyObjectHashTable.get_item() pandas\_libs\hashtable_class_helper.pxi in pandas._libs.hashtable.PyObjectHashTable.get_item() KeyError: 'addr_state:SC' The above exception was the direct cause of the following exception: KeyError Traceback (most recent call last) <ipython-input-61-eded9de2c028> in <module> ----> 1 df_inputs_prepr['addr_state:SC'] ~\anaconda3\lib\site-packages\pandas\core\frame.py in __getitem__(self, key) 2904 if self.columns.nlevels > 1: 2905 return self._getitem_multilevel(key) -> 2906 indexer = self.columns.get_loc(key) 2907 if is_integer(indexer): 2908 indexer = [indexer] ~\anaconda3\lib\site-packages\pandas\core\indexes\base.py in get_loc(self, key, method, tolerance) 2898 return self._engine.get_loc(casted_key) 2899 except KeyError as err: -> 2900 raise KeyError(key) from err 2901 2902 if tolerance is not None: KeyError: 'addr_state:SC' Because of this my code of creating state categories giving error.

In time of creating dummies I set prefix = 'status' instead od 'satate' that is why in time of merging python was unable to recall the spacific state.
