import json weather   urllib2 urlopen  url   wjson   weather read   wjdata   json loads wjson  print wjdata  data    current condition   0   temp C     What you get from the url is a json string  And your can t parse it with index directly  You should convert it to a dict by json loads and then you can parse it with index   Instead of using  read   to intermediately save it to memory and then read it to json  allow json to load it directly from the file   wjdata   json load urllib2 urlopen  url
