Retrieving key, value of json data python

Question

I have a Json file with a dictionary that looks like

{"tvs": 92, "sofas": 31, "chairs": 27, "cpus": 007}

I'm trying loop though the dictionary and print the key with its corresponding value, in my code I'm getting a too many values to unpack error.

with open('myfile.json', "r") as myfile:
json_data = json.load(myfile)
for e, v in json_data:
  for key, value in e.iteritem():
    print key, value

Answer 1

So, by default a dict will iterate over its keys.

for key in json_data:
    print key
# tvs, sofas, etc...

Instead, it seems like you want to iterate over the key-value pairs. This can be done by calling .items() on the dictionary.

 for key, value in json_data.items():
    print key, value

Or you can iterate over just the values by calling .values().

Answer 2

Try this:

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

You have an extra loop in your code, also, the input file has invalid data 007. Loading it into json should give you an error.

Is this what you're looking for?

>>> json = {"tvs": 92, "sofas": 31, "chairs": 27, "cpus": 007}
>>> for j in json:
...     print j, json[j]
... 
chairs 27
sofas 31
cpus 7
tvs 92
