python Importerror using jsonrpc2 -

-

I am trying jsonrpc2 using python I have created a file hello.py 

 < Code> def Greeting (name): return word (message = "hello,% s!"% Name)   
 Then I  
  runjsonrpc2 Hello   
 but got me  
  importError: Hello any module    
 
 
 It looks like  runjsonrpc2  is missing  hello.py module in  sys.path   
 You can increase the search path along with that directory where your  Hello  module only gives the environment settings variable  
 For example, if you are using a shell shell, you can run the following commands in the same directory of your  hello.py  file:  
  $ export PYTHONPATH = $ PYTHONPATH:. $ Runjsonrpc2 Hello

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

-
Assume that we have a feature / module, which increases a website so it is not really necessary and it I use the requestAnimationFrame , which is like IE8 / 9, I could have polyphil requestAnimationFrame , but because it is only an increase, the old browser should ignore it. The code of this module looks more or less like this: ; {Function (window, document, undefined) {'strict use'; // example module // constructor function module, option) {// ...} Module.prototype = {init: function () {// if requestAnimationFrame Not supported, a warning warning ("init") should be popped up;}, method: function () {/ if the request animationfreck is not supported, then alert any warning ("Start");}}; Window.Module = Module;} (window, document) should pop up; Then I can create a new example var example = new module (document.getElementById ('test')); and "interact with" instance.init (); Instance.method (); The problem with this code ...
