I am using below script in Multiprocessing Task:
Data_List = pool.map(self.Get_Series_Data, Series_Id_List)
Method "self.Get_Series_Data", generates Dataframe and "pool.map" stores as List in Data_List

I want to convert this list items(contains dataframe) to single Dataframe
我认为这应该工作:
single_dataframe = pd.concat(data_list)
