I got a json data that some value I need is hiding in a string, but Im not sure is there a good way to pick it out.

the data I need is an url inside the string but conclude list and dict like:

data_2 = content["a"]["b"][0]["value"]
print(type(data_2))
>>>> <class 'str'>
print(data_2)
>>>> [{"id":"123","name":"John","url":"https://www.data.com/"}]

and I have to pick up the value of url.

strip() doesnt help btw, Im still trying.
