What Steve Holden says is right. If it turns out you need to know
ahead of time, use a lagged input to determine whether it is last:
def lagged(source):
'''produce element,islast for elements in source'''
generator = iter(source)
previous = generator.next()
for element in generator:
yield previous, False
yield previous, True
file = open ('C:\some.csv','r')
reader = csv.reader(file)
for row, final in lagged(reader):
print row
if final:
print 'final:', row
else:
print 'leads:', row
