python - Plotting data from input file from command line -

-

I have given a data file named "density_air.dat" and I have to take data from each column and put them in In my lists (i.e. tList will hold values ​​in the column starting with "-10") and the density will be assumed in the column starting with "1.341". The lists need to be conspicuously then I want to pop up the lists with this data Having trouble ... Any help? 

  to scitools.std import * import sys pylab Import in the form of the enfile = sys.argv [-1] f = open (inFile, 'r') for X range (4): f.readline () tList = [] density = [] line in f For: word = line.split () in words in x: tList.append (word [x]) density .append (word [x]) f.close () conspiracy (tList, density)   
 The data file is:  
  Density of air at different temperatures in 1 hour, 1 atm pressure # Column 1: Celsius degree temperature # Column 2: density in kg / m ^ 3 -10 1.341 -5 1.316 0 1.2 9 5 1.2 1.2 9 10 1.247 15 1.225 20 1.204 25 1.184 30 1.164 # Source: Wikipedia (Search queries Density)  
  
 
 
 There is a  numpy  function called < Code> loadtxt  which load ascii files in the   arrays:   import as np import plat import sys in matplotlib.pylab File = sys.argv [-1] temperature, density = np.logtext (infile, unpack = true) plt.plot (temperature, density, 'to') plt.show ()

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...
