Python JSON Saving Data to Variable

Question

I am running this line of code,

m =requests.post(api_url + 'accounts', json=order, auth=auth)
print m.json()

which produces the following output:

[{u'available': u'0.4', u'balance': u'0.5'}, {u'available': u'6.8', u'balance': u'9.0'}]

My goal is to be able to save the different "availables" and "balances" into FLOAT variables, so I can use them further in the code.

Currently, I am trying to do

output = float(m['available'])
print(output)

But this is not working ... and I am also unsure how to separate them both, given that there is a { curly bracket} between the two "availables" and "balances"

...and when posting questions, "this is not working..." is way too vague. Tell us how its not working, preferably with a stack trace when available. You are making us guess when you have the information. — tdelaney

I think the json string you get looks like that

[
    {
        "available": "0.4",
        "balance": "0.5"
    },
    {
        "available": "6.8",
        "balance": "9.0"
    }
]

Which means m.json() will return a list with two dictionaries in it .

You should use float(json[0]['available']) to get the value .
