Hello, I need your help in designing a function. I have created this
script to check out if certain column in some csv files has value "0":
def zerofound(csvfile, outputfile, lastcolumn ):
"""Finds columns with zero prices. Column have 0 index"""
final = csv.writer(open(outputfile, 'wb'), dialect='excel')
reader = csv.reader(open(csvfile, 'rb'), dialect='excel')
for row in reader:
if '0' in row[:lastcolumn]:
if __name__ == '__main__':
zerofound('pricesfrombv.csv', 'noprices_in_BV.csv', 4)
zerofound('excelbv.csv', 'noprices_in_ExcelBV.csv', 6)
My question is. Is it OK to create functions with no "returns"?
Basically what I did resembles a subroutine, right? How could I
redesign this to use "return"?
Thanks for your input,
