haskell - Why does the operator ** fail where the operator ^ works? -

-

So, here are two lists that understand, first uses ^ while the other uses < Code> ** : 

  & gt; [X ^ 2 | X & LT; - [1..10], weird x] [1,9, 25, 49,81] & gt; [X ** 2 | X & LT; - [1..10], weird x] & lt; Interactive>: 9: 1: Any examples arising from the use of printing (Show T0) type variable ???? TA ???? Note: There are several possible examples: Show example twice - defined in GHC. Floatio Example showing float - defined GACC. Example (see Integral A, A) = & gt; Show (GHC.RialArtioA) - Define GACC. In real ... plus 23 other interactive GHCI commands in an STMT: Print it   
 As far as I know the difference between two operators is that with integers first Works, while the second floating works with point value, exactly the expected output:  
  [1.0.0.0.0, 25.0, 49.0, 0.81.0]   
 The real question is why does the understanding of the second list fail?   
 
 
 As you say that  **  works with floating ponits Although it works with  weird  only  integral  s, so understanding of your second list works only with types that are both  floating  and Examples of  integral  and such type are not present.  
 While I'm not sure why error message claims that there are 26 possible examples, when no one does mention it, then really meets the necessary obstacles.

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...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
