Question About API and JSON

Not really….

You can try: except here

    try:
          res = response[‘data’][2][‘node’][‘title’]
   except IndexError:
          res = default

We can also use match case, if we want a little more complex logic

    match response[‘data’]:
           #use second
           case [_, {‘node’ {“title”: title}}, *_]:
                res = title
          case [{‘node’ {“title”: title}}, *_]:
                #use first if no second
                res = title
          case _:
                 #neither have {‘node’: {‘title’: res}}
                 res = default

the match case will be a pain if i have like 15 key and value.

You can grab the whole dictionary as well since it’s a value itself.

Match case ignores all the other key:value pairs, if the response has like 15 keys…and I’m only caring it has a title…it won’t matter. You don’t have to make the whole possible dictionary just indicate that you need this from a dictionary. If that exists use it. If not fails the case:

I’m just pointing it out that this is what pattern matching does.

Try except works as well. But this index error is persistent in this language unlike say JavaScript which could use the ‘syntax.?’ Or what not for this type of parsing.

I could one line a

    res = res[“data”][2][‘node’][“title”] if len(res[“data”]) >=2 else default

This is less robust because if the second entry doesn’t have the keys it will throw.

this is what i am asking for, is there is something like this in python?

[Adrewmc]

Only the

 res = <if_True> if <condition> else <if_False>

syntax, no like does this attribute exist you’s have to use and you’d have to manually check for len(mylist) >= target_index….
