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...

c# - How to check if a certain method/class/API exists in Xamarin iOS? -

-
After the it is recommended to check for a specific API like this IsiOS7 bool public stable {Returns UIDevice.CurrentDevice.CheckSystemVersion (7, 0); }} If (Util.IsiOS7) {// call iOS 7 API} and {// iOS 6.1 or earlier API call} The same should go for iOS 8. Now I have read that you should check whether there is a certain method or class exists rather than checking the version. Here comes the RespondsToSelector that should be something like this if (RespondsToSelector (new selector ("edgesForExtendedLayout"))) EdgesForExtendedLayout = UIRectEdge.None. But how will one examine if a whole class exists like UIAlertController ? In Objective-C, there is no NSClassFromString I have seen in some such purpose - if ([UIAlertController class]) {// ...} Will such a move happen? type type = type Gettype ("UIAlertController"); If (type! = Null) {// iOS 8 API} other {// iOS 7 or lower} How will this happen in C #? Or to check for UIAlertController...
