Question

我正在尝试将列表写入csv文件。下面的代码运行并返回没有错误，但它不起作用，因为它实际上不填充列表中的东西csv文件。我可能做错了，因为我不明白。

import newspaper
import os
from newspaper import article
libya_newspaperlist = []
libya_newspaper=newspaper.build('https://www.cnn.com',    memoize_article=False)
for article in libya_newspaper.articles:
libya_newspaperlist.append(article.url)
import csv
os.chdir("/users/patrickharned/")
libya_newspaper.csv = "/users/patrickharned/libya_newspaper.csv"
def write_list_to_file(libya_newspaperlist):
  """Write the list to csv file."""

    with open("/users/patrickharned/libya_newspaper.csv") as outfile:
            outfile.write(libya_newspaperlist)

所以我把代码更改为了。进口报纸进口口来自报纸进口文章 libya_newspaperlist = [] libya_newspaper = newspaper.build（＆＃39; https://www.cnn.com＆＃39;，memoize_article = False）对于libya_newspaper.articles中的文章： libya_newspaperlist.append（article.url）导入csv os.chdir（＆＃34; /用户/ patrickharned /＆＃34） libya_newspaper.csv =＆＃34; /users/patrickharned/libya_newspaper.csv" 打开（＆＃34; /users/patrickharned/libya_newspaper.csv"，＆＃34; w＆＃34;）作为outfile： outfile.write（STR（libya_newspaperlist））

现在它输出到csv文件，但它只输出第一个条目而不会完成剩下的工作。有什么建议吗？

您必须以写入模式打开文件：

with open("/users/patrickharned/libya_newspaper.csv", "w") as outfile:
        outfile.write(libya_newspaperlist)

为什么我不能用csv模块创建csv文件？
