python csv文件打開錯誤：_csv.Error: line contains NULL byte

當python讀取文件出現_csv.Error: line contains NULL byte時，

# -*- coding:utf-8 -*-

import csv

with open(r'E:\abc\web_test\userinfo.csv','rb') as f:
    reader = csv.reader(f)
    rows = [row for row in reader]
    print rows

報錯：

D:\Python27\python.exe E:/abc/loop_reader.py
Traceback (most recent call last):
  File "E:/abc/web_test/loop_reader.py", line 7, in <module>
    rows = [row for row in reader]
_csv.Error: line contains NULL byte

Process finished with exit code 1

錯誤提示為：_csv.Error: line contains NULL byte

翻譯為：CSV錯誤，行包含空字節

原因：通常是因為保存時擴展名為xls或xlsx,而將其改為csv文件通常是重命名

解決方法：把它另存為.csv文件即可
