Python 使用 Pyparsing 解析逗号分隔的嵌套括号

Question

I want to parse a comma separated nested brackets into nested list:

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()

this is what i get:

why do i get ',' (a single comma) as list item or,null,null,null, for example? How to fix it?

Answer 1

It's a usual JSON, try to parse it with json package:

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)
