Divide multiple columns by another column in pandas

Question

I need to divide all but the first columns in a DataFrame by the first column.

Here\'s what I\'m doing, but I wonder if this isn\'t the \"right\" pandas way:

Answer 1

I believe df[['B','C']].div(df.A, axis=0) and df.iloc[:,1:].div(df.A, axis=0) work.
