Divide two dataframes with multiple columns (column specific)

Question

I have two identical sized dataframes (df1 & df2). I would like to create a new dataframe with values that are df1 column1 / df2 column1. So essentially df3 = df1(c1)/df2(c1), df1(c2)/df2(c2), df1(c3)/df2(c3)...

I've tried the below code, however both give a dataframe filled with NaN

#attempt 1
df3 = df2.divide(df1, axis='columns')
#attempt 2
df3= df2/df1

Answer 1

You can try the following code:

df3 = df2.div(df1.iloc[0], axis='columns')

Answer 2

To use the divide function, the indexes of the dataframes need to match. In this situation, df1 was beginning of month values, df2 was end of month. The questions can be solved by:

df3 = df2.reset_index(drop=True)/df1.reset_index(drop=True)
df3.set_index(df2.index,inplace=True) ##set the index back to the original (ie end of month)
