Hi All,
I'm trying to use the CSV module to read in some data and then use a
hashable method (as there are millions of records) to find unique ids
and push these out to another file,
can anyone advise? Below is the code so far
fin = open(CSV_INPUT, "rb")
fout = open(CSV_OUTPUT, "wb")
reader = csv.reader(fin, delimiter=chr(254))
writer = csv.writer(fout)
headerList = reader.next()
UID = {}
#For help
#print headerList
# ['Time', 'User-ID', 'IP']
try:
for row in reader[1]:
UID[row] = 1
else:
List= UID.keys()
writer.writerows(List)
fin.close()
fout.close()
Mike
