求助，刚学python，有个问题无法解决！

Posted 2023-02-18

使用python 2.7版本！
源码：
# -*- coding: utf-8 -*-
import csv
from io import open

g_record = [];

a = [1,2,3];
b = [2,5,5];
g_record.append(a);
g_record.append(b);

fd = open("newrecord.csv","w+")
writer = csv.writer(fd)
for line in g_record:
writer.writerow(line);
fd.close()

错误：
Traceback (most recent call last):
File "Script1.py", line 15, in <module>
writer.writerow(line);
TypeError: must be unicode, not str

参考技术A fd = open("newrecord.csv","w+")
改成
fd = open("newrecord.csv","wb+")
用二进制方式打开就ok了 参考技术B # -*- coding: utf-8 -*-
import csv
from io import open

g_record = []

a = [1,2,3]
b = [2,5,5]
g_record.append(a)
g_record.append(b)

fd = open("newrecord.csv","wb")
writer = csv.writer(fd)
for line in g_record:
print line
writer.writerow(line)
fd.close()
