Question

I am trying to traverse each ‘node?’ of a JSON objet in python. I am trying to implement a recursive function like

def function(data):
         for element in data:
                --- do something----
                if (some condition):
                        function(element)

what I want to know is how can I find if the element in question is another object or just a string. That is, what should I write instead of ‘some condition’ in my above code. Like when I travese an XML , I check if it has any children using getchildren() and if it does, I recursively call the function again…..

A good pythonic way to do it could be something like this :

def function(data):
   try:
      for element in data:
         --- do something----
         function(element)
   except TypeError:
      pass

Do the stuff and let python raise an exception if you try to iterate on something that is not iterable 😉
