根据其文档,csv.writer默认情况下应使用'\ r \n'作为lineterminator.

import csv

with open("test.csv", "w") as f:
    writer = csv.writer(f)

    rows = [(0,1,2,3,4),
           (-0,-1,-2,-3,-4),
           ("a","b","c","d","e"),
           ("A","B","C","D","E")]           

    print writer.dialect.lineterminator.replace("\r", "\\r").replace("\n", "\\n")
    writer.writerows(rows)
    print writer.dialect.lineterminator.replace("\r", "\\r").replace("\n", "\\n")

这打印

\r\n
\r\n

正如所料.但是,创建的csv文件使用了行终止符'\ r \n\r \n'

0,1,2,3,4

0,-1,-2,-3,-4

a,b,c,d,e

A,B,C,D,E

这是一个错误还是我使用csv.writer时出了什么问题？
