预期的字符串或缓冲区错误

Question

Can anyone please tell me whats wrong with this block of code. It is for reading line starting with 'READ' on a csv file. The error I am getting is return _compile(pattern, flags).match(string) TypeError: expected string or buffer

import csv
import re
f1 = open("1.csv", "rb")
reader = csv.reader(f1)
header = reader.next()
f2 = open("out.csv", "wb")
writer = csv.writer(f2)
writer.writerow(header)
for row in reader:
if re.match(r'^.*READ $', row):
writer.writerow(row)
f1.close()
f2.close()

Answer 1

Indent your code number 1...

This may work...

import csv
import re

f1 = open("1.csv", "rb")
reader = csv.reader(f1)
header = reader.next()
f2 = open("out.csv", "wb")
writer = csv.writer(f2)

writer.writerow(header)
for row in reader:
    if re.match(r'^.*READ $', str(row)):
        writer.writerow(row)

f1.close()
f2.close()
