This can be useful if you are using Python primarily for the enhanced control flow it offers over most system shells and still want convenient access to other shell features such as shell pipes, filename wildcards, environment variable expansion, and expansion of ~ to a user’s home directory.However, on cygwin, output from bash isn't the same as from Python's subprocess, viz:Bash:
$ ls -ls ~rbarakx
total 0

Python:
>>> subprocess.call(,shell=True)

It looks as if subprocess.call is executing just ls.Can you suggest why?My Environment:Python: Python 2.7.3 (default, Dec 18 2012, 13:50:09) on cygwincygwin: CYGWIN_NT-6.1-WOW64 ... 1.7.22(0.268/5/3) ... i686 Cygwinwindows: Windows 7 Ultimate less

I want to tokenize group of words. For example Data Science is a keyword when i tokenize i will get data and science separately. How to overcome this situation. Is there any library which does these extraction in python?

def quad(x, a, b, c):
return a*x**2 + b*x + c
As you may notice it contains several parameters (viz. a, b, c) apart from the variable x. Now if I were to put this in a file and simply import it, the end user would have to always call the function with the parameters in addition to the variable. Because of this I was thinking of creating a class such as this:
class quad:
def __init__(self, a, b, c):
self.a = a
self.b = b
self.c = c
def eq(x):
return self.a*x**2 + self.b*x + self.c
Thus allowing the end user to use it as:
q = quad(p, q, r)
eq = q.eq
Is this the right way of doing things? I am terribly sorry about the title of the question, as I... less

I'm trying to wrap my head around the concept of "training a model" or a "trained model" in data science, and deploying that trained model.
I'm not really concerned about the deployment environment, automation, etc.. I'm trying to understand the deployment unit.. a trained model. What does a trained model look like on a file system, what does it contain?
I understand the concept of training a model, and splitting a set of data into a training set and testing set, but lets say I have a notebook (python / jupyter) and I load in some data, split between training/testing data, and run an algorithm to "train" my model. What is my deliverable under the hood? While I'm training a model I'd think there'd be a certain amount of data being stored in memory.. so how does that become part of the trained model? It obviously can't contain all the data used for training; so for instance if I'm training a chatbot agent (retrieval-based),... less

But as a circular graph with crossing edges, it is a pure hierarchy, and it seems I ought to be able to display it as a tree.
I have googled this extensively, and every solution offered involves using pygraphviz... but" PyGraphviz does not work with Python 3 (documentation from the pygraphviz site)."
Has anyone been able to get a tree graph display in Python 3?

Link for the graphic visualization: http://www.census.gov/dataviz/visualizations/stem/stem-html/
Which kind of visualization is this? is it a piechart or any other different kind of graphic visualization.
Are there any APIs available to create such a visualization or do i need to use any web service?

I want to plot a correlation matrix which we get using dataframe.corr() function from pandas library. Is there any built-in function provided by the pandas library to plot this matrix?
So far I have been unable to find an R library that can create a sunburst plot like those by John Stasko. Anyone knows how to accomplish that in R or Python?
