如何在python中刪除字符串周圍的引號？

Question

我正在嘗試刪除data[clonedRadarsdetailslist]存在的所有元素的引號，如下所示，我看到2個問題，有人可以提供解決此問題的指南嗎？

1.行情不會被刪除

2.執行腳本后，並非所有元素都存在，可能是因為我覆蓋了

import datetime
data = {'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': ["{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}", "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"]}
print data
for radardetails in data['clonedRadarsdetailslist']:
    radardetails = radardetails.strip('\"')
    data['clonedRadarsdetailslist'] = radardetails

print data

當前結果：

{'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"}

預期結果：

{'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': [{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}, {'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}]}

Answer 1

您收到的錯誤告訴您單引號無效。 您可以在嘗試加載之前用雙引號替換它們：

>>> [json.loads(x.replace("'", '"')) for x in data['clonedRadarsdetailslist']]

[{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'},
 {'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}]

另外，對正在循環的容器進行突變也是一個壞主意。 不要那樣做！

import datetime
import json

data = {

  'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953),
  'clonedRadarsdetailslist': [
    "{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}",
    "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"
    ]}

data['clonedRadarsdetailslist'] = [json.loads(x.replace("'", '"'))
  for x in data['clonedRadarsdetailslist']]

print(data)

您有一個key：value JSON'dictionary'，需要將其轉換為一系列數組才能遍歷值。 您需要使用JSON.loads()函數來完成此操作。 我不確定100％確定所需的值，也不確定是否要更改代碼以適應除其他代碼之外的任何特定值，因為我不確定所需的值，但這應將JSON數據轉換為超級數組可以循環通過：

import datetime
data = {'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': ["{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}", "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"]}
json = json.loads(data)
for radardetails in json['clonedRadarsdetailslist']:
    radardetails = radardetails.strip('\"')
    data['clonedRadarsdetailslist'] = radardetails

print json

應該可以工作，但不確定要從中實際獲得什么，但是您需要將JSON轉換為一系列數組，然后遍歷它們以獲取必要的值。

編輯 ：真的很抱歉跳槍並假設我知道發生了什么。 您有一本不像我最初想的那樣的字典。 這是一個可以為您提供多種信息的解決方案，您可以從此處獲取所需的任何信息：

import datetime
data = {'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': ["{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}", "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"]}
list = []
for key, value in data.items():
    temp = [key,value]
    list.append(temp)

for item in list:
    print (item)

編輯2 ：只是完善代碼以更好地滿足您的需求，現在（我希望）它將提供您想要的功能：

import datetime
import ast
data = {'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': ["{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}", "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"]}
list = []
radarlist = []
for key, value in data.items():
    temp = [key,value]
    list.append(temp)

radar = ast.literal_eval(list[2][1][0])

for key, value in radar.items():
    temp = [key,value]
    radarlist.append(temp)

for item in radarlist:
    print(item)

Answer 3

像這樣使用eval怎么辦：

import datetime, json
data = {'orgRadar': u'37125110', 'created_on': datetime.datetime(2018, 5, 10, 22, 48, 46, 979953), 'clonedRadarsdetailslist': ["{'clonedRadar': 40145048, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}", "{'clonedRadar': 40145054, 'clonedStatus': 'PASS', 'clonedRadarFinalStatus': 'PASS', 'updatedFailedReason': 'N/A', 'clonedRadarFinalStatusReason': 'N/A', 'updateStatus': 'PASS', 'clonedStatusfailReason': 'N/A'}"]}

data['clonedRadarsdetailslist'] = eval(data['clonedRadarsdetailslist'][0])
print data
