python - 如何删除 python 中字符串周围的引号？

Question

我正在尝试删除 data["clonedRadarsdetailslist"] 中存在的所有元素的引号，如下所示。

1. 引用不会被删除

2. 脚本执行后并非所有元素都存在，可能是因为我正在覆盖

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

当前结果:

{'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'}"}

预期结果:

{'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

您收到的错误告诉您单引号无效。您可以在尝试加载之前用双引号替换它们:

>>> [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'}]

此外，改变您正在循环的容器是个坏主意。不要那样做!

编辑:根据要求提供“完整解决方案”。

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

print(data)
