How do I query this (json looking) data? - Python : I have this data coming via an api and I want to pull all the "confidence" scores that are in there. How would I go about doing that:

    b'{"time":765,"annotations":[{"start":106,"end":115,"spot":"customers","confidence":0.7198,"id":234206,"title":"Customer","uri":"h'

    b'pot":"small","confidence":0.7233,"id":276495,"title":"Small business","uri":"http://en.wikipedia.org/wiki/Small_business","label'

    b',{"start":268,"end":290,"spot":"social media marketing","confidence":0.7992,"id":21179478,"title":"Social media marketing","uri"'

    b'"end":463,"spot":"exposure","confidence":0.6613,"id":245583,"title":"Publicity","uri":"http://en.wikipedia.org/wiki/Publicity","'

    b'5,"spot":"risks","confidence":0.6431,"id":26404,"title":"Risk management","uri":"http://en.wikipedia.org/wiki/Risk_management","'
    b'label":"Risk management"}...}

I tried doing things like data["confidence"], but it didn't seem to pull the confidence figures. How do I pull the confidence figures in Python? Thank you in advance.
