Question

我有将列表列表写入CSV文件的脚本。除一个问题外，工作正常：数据中的某个列总是被截断为输出文件中的256个字符。我在写入之前检查了数据（使用“print”命令），它似乎包含全长（~600个字符）。更奇怪的是，还有另一列具有典型数据~1000个字符且不会被截断。

编辑：这是一个可以重现问题的最小代码。请注意，第二个字符串比第三个字符串短得多，但它仍然在csv中被截断，但第三个字符串完全写入而没有截断。

import csv
mylist = [[0.43,
          "+/Men-s-Casual-British-Style-Canvas-Sports-Shoes--0.jpg::Men's Casual British Style Canvas Sports Shoes ;+/Men-s-Casual-British-Style-Canvas-Sports-Shoes--1.jpg::Men's Casual British Style Canvas Sports Shoes ;+/Men-s-Casual-British-Style-Canvas-Sports-Shoes--2.jpg::Men's Casual British Style Canvas Sports Shoes ;+/Men-s-Casual-British-Style-Canvas-Sports-Shoes--3.jpg::Men's Casual British Style Canvas Sports Shoes ;+/Men-s-Casual-British-Style-Canvas-Sports-Shoes--4.jpg::Men's Casual British Style Canvas Sports Shoes ;+/Men-s-Casual-British-Style-Canvas-Sports-Shoes--5.jpg::Men's Casual British Style Canvas Sports Shoes ",

with open("test.csv", mode='wb') as f:
    dataWriter = csv.writer(f)
    dataWriter.writerows(mylist)

有没有人遇到过这个？任何暗示都会有所帮助。我使用Python 2.7（Anaconda发行版）

感谢。
