How to delete rows (NOT columns) in a csv file

I am trying to delete a particular row (NOT a column) in a csv file for a class project. When I deleted columns I put:

r=row r[22], r[21]# and so on

So how do I specify that I want to delete rows? I am working with census data and want to get rid of that extra row of headers that are always in census tables.Thank you for any help.
