I know the problem is with the for loop but don't know how to fix. Any help
with explanation would be appreciated.
#!/bin/env python
import csv
import sys
if len(sys.argv) < 3:
print('Please specify a filename and column number: {} [csvfile]
[column]'.format(sys.argv[0]))
sys.exit(1)
filename = sys.argv[1]
column = int(sys.argv[2])
for line in filename() , column ():
elements = line.strip().split(',')
values.append(int(elements[col]))
csum = sum(values)
cavg = sum(values)/len(values)
print("Sum of column %d: %f" % (col, csum))
print("Avg of column %d: %f" % (col, cavg))
