python - how to extract a zero-dimensional slice from a 1-dimensional array in numpy -

-

Is a 1-dimensional array slice the zero-dimensional sub-array?

ndarray arr , arr [0] (N-1 ) - Dimensional Ndarray .

However, if I have 1-dimensional ndarray x , x [0] 0-dimensional ndarray is not back Returns, rather a numpy.int64 , (if x contains int64 s).

The minimum example: 

  def increment (zero_d_array): zero_ad_rere [...] = zero_a_array + 1 counter = mmp.re (0) # zero-dimensional with scalar Array increments (counter) # Success; Counter now 1 counter = numpy.zeros (3, dtype = int) # [0, 0, 0] increment (counter [1]) # failed; Counter [1] is a numpy.int64, not 0-D array   
 I realize that  will work with increments (counter [1: 2]) , But only because  increments ()  works with both 0-D and 1-D input, all functions will be so flexible.   
 
 
 Use an oval:  
  increment (counter [ 1, ...])

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...
