未知的轉義字符問題蟒蛇

使用YAML當我有它轉換成JSON字典類型時產生麻煩以下文本（以大熊貓數據幀的小區之一）：未知的轉義字符問題蟒蛇

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

我的代碼使用是這樣的：

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

它引發以下錯誤：

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

當我打印特定細胞，這是我得到

df.ix[7, 'POST'] 

>> that\\\'s

我已經檢查了SO和YAML指南已經其他相關的問題，但無法找出解決的辦法是什麼。有人可以幫忙嗎？

它看起來像你試圖應用'YAML'而不是'JSON'。試試'json.loads'而不是 – MaxU

@MaxU謝謝！剛剛得到了一個類似的錯誤'無效\轉義：第1行第173列'！ – renakre

@MaxU：請注意，YAML是JSON的超集。也就是說，YAML解析器將解析任何有效的JSON文檔。 – larsks

您必須先刪除轉義字符，因爲JSON不允許它。

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("\\'", "'"))

編輯：

爲@larks中的評論稱，

that ' doesn't need to be escaped (because the string is enclosed in double quotes)

，事實上你的問題是難以重現：

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)

將兩個輸出：

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