Merge multiple dataframs
from functools import reduce Name of a column in all dataframes is 'DATE' df_merged = reduce(lambda left,right: pd.merge(left,right,on=['DATE'], how='outer'), data_frames) # if you want to fill the values that don't exist in the lines of merged dataframe simply fill with required strings as df_merged = reduce(lambda left,right: pd.merge(left,right,on=['DATE'], how='outer'), data_frames).fillna('void')
