像这样。

这是因为导入的时候，是这样写的：

with open('book_statics.csv', 'w+') as csvfile:    writer = csv.writer(csvfile)    for i in ans:        writer.writerow(i)

只要改成wb+,也就是写二进制文件，就好了吗？

with open('book_statics.csv', 'wb+') as csvfile:    writer = csv.writer(csvfile)    for i in ans:        writer.writerow(i)

 并没有！！！

报错：TypeError: a bytes-like object is required, not 'str'

查阅了官方文档，改成如下即可

with open('book_statics.csv', 'w+', newline='') as csvfile:    writer = csv.writer(csvfile)    for i in ans:        writer.writerow(i)

　　

成功解决。
