Access JSON to DICT in Python -


i have next json in js

var intervalos= {           "operandos":[{              "extremoinferior":$(edit_numvar).context.value,              "extremosuperior":$(edit_numvar2).context.value           },           {              "extremoinferior":$(edit_numvar3).context.value,              "extremosuperior":$(edit_numvar4).context.value           }] };

and did parsed_input = json.loads(self.intervalos)

but don't know how access dict. tried 

intervalos[operandos][extremoinferior])

but returns error.

could me accessing element of dict?

after deserializing json python object access elements. example: 

parsed_input = json.loads(self.intervalos) extremo_inferior_0 = parsed_input['operandos'][0]['extremoinferior']
