Answer 1

I think this does what you want:

import csv

with open('C:/Python27/testweight.csv', 'r', newline='') as f:
    reader = csv.reader(f, delimiter='\t')
    header = next(reader)
    rows = [header] + [[row[0], int(row[1])] for row in reader if row]

for row in rows:
    print(row)

Output:

['Account', 'Value']
['ABC', 6]
['DEF', 3]
['GHI', 4]
['JKL', 7]
