一段字符串，如何提取里面的列表？

本帖最后由 hellolouis 于 2021-3-3 11:16 编辑

弄个查违章的小程序，其中代码如下：

data = urllib.parse.urlencode(data).encode('utf-8')

response = urllib.request.urlopen(url,data)
html = response.read().decode('utf-8')

print(html)


返回的是：

有几个疑问，
如何才能打印出Unicode编码转成中文呢？
如何才能提取返回里06-11行的列表呢？

把网址发出来啊

>>> address="\u5e7f\u6cb3\u9ad8\u901f2\u516c\u91cc230\u7c73\uff08\u5e7f\u6cb3\u9ad8\u901f\u51e4\u51f0\u5c71\u96a7\u9053\u8def\u6bb5\uff09\uff08\u4e1c\u5f80\u897f\uff09"
>>> print(address.encode(encoding="utf-8").decode(encoding="utf-8"))
广河高速2公里230米（广河高速凤凰山隧道路段）（东往西）
>>>

print(jsontxt["data"]["lists"])
这里注意，有两处字符串表达式不合规，自己简单的修改一下

运行效果：

D:\wp>py wp2.py
[{'time': '2021-02-21 11:26:27', 'address': '广河高速2公里230米（广河高速凤凰山隧道路段）（东往西）', 'fine': 150, 'point': 3, 'handled': 0, 'violation_type': '驾驶中型以上载客载货汽车、危险物

忽然发现，python 自己会识别这种编码的

>>> address="\u5e7f\u6cb3\u9ad8\u901f2\u516c\u91cc230\u7c73\uff08\u5e7f\u6cb3\u9ad8\u901f\u51e4\u51f0\u5c71\u96a7\u9053\u8def\u6bb5\uff09\uff08\u4e1c\u5f80\u897f\uff09"
>>> print(address.encode(encoding="utf-8").decode(encoding="utf-8"))
