Python无法访问字典

Question

Getting TypeError: string indices must be integers when trying to access a dictionary in python. I've tried using json.loads(r2) thos produces "TypeError: the JSON object must be str, bytes or bytearray, not dict"

Not even sure if Im on the right track here, all I need to do is get the JSON which appears to be in one long string into something like x['SomeKey'] and the value at those keys using iteritems() or similar?

r = requests.get(url, headers=headers)
r2 = r.json()
seq = json.dumps(r2)
print(seq['remotecontrol_id'])

Answer 1

r.json() already returns a dictionary so I'm not sure why you pass r2 to json.dumps that returns a string (hence the s ). The error message you received even suggests that ("TypeError: the JSON object must be str, bytes or bytearray, not dict ")

Your code should be

r = requests.get(url, headers=headers)
r2 = r.json()
print(r2['remotecontrol_id'])

Answer 2

The problem is that method dumps converts a python's dictionary into a string , therefore in the line seq['remote...'] you are accessing a string . You should access the variable r2 instead of seq

Answer 3

Ok, I got it figured out, sort of...

for i in r2:

print(r2['stuff'][0]['someval1']) print(r2['stuff'][1]['asomeval2'])

Anyway, hits works

Thanks for all the great advice!
