Python使用Pyparsing解析逗号分隔的嵌套括号

Question

我想将逗号分隔的嵌套括号解析为嵌套列表：

from pyparsing import nestedExpr
str = r'[["http://google.com","Jose Rivas","http://google.com","some_guid"],"a year ago",null,null,4,null,"1003136023",["https://www.yahoo.com","Do it",null,"0ahU_pv"],null,null,"ChZDSUhNMG","0ahUKEwjBr"]'

z = nestedExpr('[', ']').parseString(str).asList()

这就是我得到的：

为什么要将“，”（一个逗号）作为列表项，或者，例如，null，null，null？ 如何修复它

Answer 1

这是一个常见的JSON，请尝试使用json包解析它：

import json

raw = r'[["http://google.com","Jose Rivas","http://google.com","some_guid"],"a year ago",null,null,4,null,"1003136023",["https://www.yahoo.com","Do it",null,"0ahU_pv"],null,null,"ChZDSUhNMG","0ahUKEwjBr"]'
data = json.loads(raw)

print(data)
