Read specific columns from a csv file with csv module?

Question

I\'m trying to parse through a csv file and extract the data from only specific columns.

Example csv:

ID | N

To fetch column name, instead of using readlines() better use readline() to avoid loop & reading the complete file & storing it in the array.

with open(csv_file, 'rb') as csvfile:

    # get number of columns

    line = csvfile.readline()

    first_item = line.split(',')
