Divide Multiple Columns by Multiple other Columns

For two dataframes:

 df_1 = pd.DataFrame({'A': [1, 2], 'B': [3, 4]}) 

 df_2 = pd.DataFrame({'A': [3], 'B': [4]})

How do I divide all values in df_1 columns A and B by the respective values of A and B in df_2 so that:

 df_3 = pd.DataFrame({'A': [0.33, 0.66], 'B': [0.75, 1]})

I need to perform this operation over two large dataframes with the same headings. Please, scalable solutions.

>Solution :

You can use slicing of df_2 as Series:

df_1.div(df_2.iloc[0])

Or:

df_1.div(df_2.squeeze())

Output:

          A     B
0  0.333333  0.75
1  0.666667  1.00
