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()

这是我得到的：

为什么我得到“,”（一个逗号）作为列表项或 ,null,null,null，例如？如何解决？

Answer 1

这是一个普通的JSON，尝试用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)
