How do I intertwine columns?

I have created a pivot table where I need to weave in columns “A” and “One” for each year but I’m not sure how to do that. So far, I have a regular pivot table.

df_pivot=df.pivot(index=[‘Col1’, ‘Col2’, ‘Col3’], values=[‘A’, ‘One’], columns=[‘Year’]
).reset_index()

So my results should show each year (2000, 2001, 2002…) with their own “A” and “One” column.

If anyone can point me in the right direction. Thanks!
