python - 如何将 JSON 字段中的多个段落连接成 .txt 中的一个段落？

Question

我正在尝试将来自多个段落的评论连接成一个——我正在尝试这样做:

for x in docs:
   with open(fp) as data_file:
     data_item = json.load(data_file)
     b = data_item['reviews']
     for item in b:
        name = '000' + str(counter) + '.txt'
        file = open(name, 'wb')
        output = item['text']
        " ".join(output.split())
        counter = counter+1
        file.write(output.encode('utf-8'))
        file.close()

但是它不起作用；每个 .txt 输出文件在 JSON 字段中都是原样(带有\n\n)...

示例 JSON:

{ "reviews": [ { "created": "2008-07-09T00:00:00", "text": "There's something reassuring etc. \n\nThe band's skill etc. \n\nCraig Finn's vocals etc.\n", }, "votes_negative": 0, "votes_positive": 0 } ] }

结果输出(.txt):

There's something reassuring etc.

The band's skill etc.

Craig Finn's vocals etc.

非常感谢。

您不将 join 的输出分配给变量，试试这个:

# sidenote: use enumerate to replace counter
for counter, item in enumerate(b):
    name = '000' + str(counter) + '.txt'
    output = item['text']
    output = ' '.join(output.split())

    # imho with is always nicer than open/close
    with open(name, ‘wb’) as file:
        file.write(output.encode(‘utf-8’))
