Question

I try to get item from dict, which was decoded by json:

data = [ { 'a':'A', 'b':(2, 4), 'c':3 } ]
data_string = json.dumps(data)
decoded = json.loads(data_string)
decoded['c']

So it shows the next:

Traceback (most recent call last):
  File "", line 1, in 
TypeError: list indices must be integers, not str

I try to print the value of c on screen
So I try to see 3 after decoded[‘c’]
How can I do this ?

Thanks!

Answer 1

your data is a list containing a dictionary

you can use decoded[0]['c'] since the dictionary is the first element of the list

another possibility is that you should use data = {u'a': u'A', u'c': 3, u'b': [2, 4]} (no square brackets)

It really depends on whether you mean for data to be a list of dictionaries or just a dictionary
