python - python CSV 和 JSON 文件的编码/解码故障排除

Question

我最初转储了一个包含特定句子的文件，使用:

 with open(labelFile, "wb") as out:
        json.dump(result, out,indent=4)

JSON 中的这句话看起来像:

"-LSB- 97 -RSB- However , the influx of immigrants from mainland China , approximating NUMBER_SLOT per year , is a significant contributor to its population growth \u00c3 cents \u00c2 $ \u00c2 `` a daily quota of 150 Mainland Chinese with family ties in LOCATION_SLOT are granted a `` one way permit '' .", 

然后我继续通过以下方式加载它:

with open(sys.argv[1]) as sentenceFile:
    sentenceFile = json.loads(sentenceFile.read())

对其进行处理，然后使用以下方法将其写入 CSV:

with open(sys.argv[2], 'wb') as csvfile:
    fieldnames = ['x','y','z'
                  ]
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
    writer.writeheader()
    for sentence in sentence2locations2values:
         sentence = unicode(sentence['parsedSentence']).encode("utf-8")
         writer.writerow({'x': sentence})

在Excel for Mac中打开的CSV文件中的句子是:

-LSB- 97 -RSB- However , the influx of immigrants from mainland China , approximating NUMBER_SLOT per year , is a significant contributor to its population growth à cents  $  `` a daily quota of 150 Mainland Chinese with family ties in LOCATION_SLOT are granted a `` one way permit '' .

然后我继续将它从 Mac 版 Excel 转移到 Google 表格，它位于:

-LSB- 97 -RSB- However , the influx of immigrants from mainland China , approximating NUMBER_SLOT per year , is a significant contributor to its population growth à cents  $  `` a daily quota of 150 Mainland Chinese with family ties in LOCATION_SLOT are granted a `` one way permit '' .

注意，略有不同，Â 已替换 Ã。

然后标记它，将它带回 Excel for Mac，此时它又变成了:

-LSB- 97 -RSB- However , the influx of immigrants from mainland China , approximating NUMBER_SLOT per year , is a significant contributor to its population growth à cents  $  `` a daily quota of 150 Mainland Chinese with family ties in LOCATION_SLOT are granted a `` one way permit '' .

我最初如何阅读 CSV，包含如下句子:

-LSB- 97 -RSB- However , the influx of immigrants from mainland China , approximating NUMBER_SLOT per year , is a significant contributor to its population growth à cents  $  `` a daily quota of 150 Mainland Chinese with family ties in LOCATION_SLOT are granted a `` one way permit '' .

值为:

"-LSB- 97 -RSB- However , the influx of immigrants from mainland China , approximating 45,000 per year , is a significant contributor to its population growth \u00c3 cents \u00c2 $ \u00c2 `` a daily quota of 150 Mainland Chinese with family ties in Hong Kong are granted a `` one way permit '' .", 

以便它与问题开头的原始 json 转储中的内容相匹配？

编辑

我从这里检查并发现 \u00c3 到 Ã 的编码，即 Google 表格中的格式，实际上是 Latin 8。

编辑

我运行了 enca 并看到原始转储文件是 7 位 ASCII 字符，而我的 CSV 是 unicode。所以我需要作为 unicode 加载并转换为 7 位 ASCII？

Answer 1

我找到了解决这个问题的方法。解决方案是将 CSV 文件从其原始格式(标识为 UTF-8)解码，然后句子变为原始格式。所以:

csvfile = open(sys.argv[1], 'r')

fieldnames = ("x","y","z")
reader = csv.DictReader(csvfile, fieldnames)
next(reader)

for i,row in enumerate(reader):
    row['x'] = row['x'].decode("utf-8")

非常奇怪的是，当我在 Excel for Mac 中编辑 CSV 文件并保存时，每次它似乎都转换为不同的编码。我警告其他用户注意这一点，因为这非常令人头疼。
