My CSV file has multiple columns. I need to delete the last column using Python. How can I do that? Could I use the CSV module? Thank you

Thanks. We'll let you know when a new response is added.
import csv
with open(“source”,”rb”) as source:
    rdr= csv.reader( source )
    with open(“result”,”wb”) as result:
        wtr= csv.writer( result )
        for r in rdr:
            wtr.writerow( (r[0], r[1], r[3], r[4]) )

— BTW, the for loop can be removed, but not really simplified.

        in_iter= ( (r[0], r[1], r[3], r[4]) for r in rdr )
        wtr.writerows( in_iter )

            del r[2]
            wtr.writerow( r )
