Enumerate JSON return

How do you enumerate a JSON return? The goal is to get a total count variable to add to my print statment...

I have 

for i in services_js["reports"]:
            print " Service Name: " + i["instances"]["serviceName"]

and have tried:

for i in enumerate(services_js["reports"]):
            print " Service Name: " + i["instances"]["serviceName"]

but get:

TypeError: tuple indices must be integers, not str
Solution

  • This is NOT how enumerate works:

    for i in enumerate(services_js["reports"]):
    print " Service Name: " + i["instances"]["serviceName"]

    It works like this:

    animals = ['rat', 'cat', 'mouse', 'dog']
for i, animal in enumerate(animals, start=1):
    print('# {}: {}'.format(i, animal))

    Notice how enumerate returns a tuple, (i and animal) not just the count?

    You may have other issues (in your JSON) but that part might be throwing you off.

    The error you are seeing is because i is actually the tuple (0, some_json) and then you're trying to do i['instance'], so it's saying you can't use a string as an index to a tuple.
