Getting Json dictionary/list values python

Question

I have a json file with a dictionary, and lists inside that dictionary

{"Dogs": [["spot"], 1], "Cats": [["whiskers"], 1], "fish": [["bubbles", "lefty", "tank", "goldie"], 4], "elephant": [["tiny", "spring"], 2], "zebra": [[], 1], "gazelle": [["red", "blue", "green", "yellow", "gold", "silver"], 6]}

There's more in the dictionary but from this example you can see the format.

with open('myfile.json', 'r') as myfile:
json_data = json.load(myfile)
for e,([v], z) in json_data.items():
  print e, v, z

This gives me a

too many values to unpack error.

I want the output to look like

dogs spot 1
cats whiskers 1

What do you want to happen for fish? You cant unpack into a list. — L3viathan

What should the output be when there are multiple things in the lists? — Paul Rooney

Presuming you want all animal names (?) output

...
for e, (v, z) in json_data.items():
    print('%s %s %d' % (e.lower(), ' '.join(v), z))

outputs

gazelle red blue green yellow gold silver 6
fish bubbles lefty tank goldie 4
cats whiskers 1
zebra  1
elephant tiny spring 2
dogs spot 1

much simpler since the value is always going to be a list:

with open('myfile.json', 'r') as myfile:    
    json_data = json.load(t)
    for e, v in json_data.items():
        print e, " ".join(v[0]), v[1]

This gives:

gazelle red blue green yellow gold silver 6
fish bubbles lefty tank goldie 4
Cats whiskers 1
zebra  1
elephant tiny spring 2
Dogs spot 1
