merge - How to connect two pandas data frames from right and left? -

-

is there way following in more elegant way (i.e. fewer commands):

df_1 = pandas.dataframe({'col1':[1,2,3], 'col2':[10,20,30]}) df_2 = pandas.dataframe({'col3':[100,200,300], 'col4':[1000,2000,3000]})  col in ['col3','col4']:     df_1[col] = df_2[col]  print df_1

you can use concat

in [407]: pd.concat([df_1, df_2], axis=1) out[407]:     col1  col2  col3  col4 0     1    10   100  1000 1     2    20   200  2000 2     3    30   300  3000
