Question

我有以下文本（pandas数据框中的一个单元格），在将其转换为json字典类型时会产生麻烦：

 {"options_selected":{"Ideas":"0"},"criterion_feedback":{},
  "overall_feedback":"...and that\'s something I want to learn too. ",
  "submission_uuid":"b195603a-60f5-11e4-95a7-0a7da95da37f"}

我使用的代码是：

df['POST'] = df['POST'].apply(yaml.load)

它会抛出以下错误：

found unknown escape character "'"
  in "<unicode string>", line 1, column 174:
     ... that\'s something I want to learn too ...

当我打印特定单元格时，这就是我得到的

df.ix[7, 'POST']

>> that\\\'s

我已经在SO和YAML指南中检查了其他相关问题，但无法弄清楚解决方案是什么。有人可以帮忙吗？

您必须首先删除转义字符，因为JSON不允许它。

to_date

编辑：

正如@larks在评论中所说，

import json j = '{"options_selected":{"Ideas":"0"},"criterion_feedback":{}, "overall_feedback":"...and that\'s something I want to learn too. ", "submission_uuid":"b195603a-60f5-11e4-95a7-0a7da95da37f"}' json.loads(j.replace("\\'", "'"))不需要转义（因为该字符串包含在 double 引号中）

确实你的问题难以重现：

将输出：

import yaml
import json

data = """
    options_selected: 
        Ideas: '0'
    criterion_feedback: {}
    overall_feedback": ...and that\'s something I want to learn too. ,
    submission_uuid : b195603a-60f5-11e4-95a7-0a7da95da37f
"""

print yaml.load(data)

j = '{"options_selected":{"Ideas":"0"},"criterion_feedback":{}, "overall_feedback":"...and that\'s something I want to learn too. ", "submission_uuid":"b195603a-60f5-11e4-95a7-0a7da95da37f"}'

print json.loads(j)

在python中使用YAML时出现未知的转义字符问题
