Siva Chandran P: TermEmulator 1.0 Released!!! - 0 views

  • The module comes with a demo application which is written in wxWidgets. The demo emulates any terminal program inside a text box. The following are the screenshots of emulating bash, emacs and vi using TermEmulator and the demo. successfully emulated(ran in a text box) bash, emacs, vi and some other terminal programs.
  • Provides callback for updating terminal screen
  •  
    I'm hoping this means that you can access the items in the terminal window via an external Python script..

Plotting NaNs in Matplotlib (matplotlib-users) - 0 views

  • Your example works as you describe on recent matplotlib versions. I suspect you are using an old one. The preferred way of handling missing points in numpy, and therefore in matplotlib and pylab, however, is via masked arrays.import pylabimport numpy as npfrom numpy import maa = [1,2,3,4,5]b = np.array([6,2,np.nan,1,9])bm = ma.masked_where(np.isnan(b), b)pylab.plot(a,bm)pylab.show()There are many other examples of masked array use in the examples directory of the matplotlib distribution.EricFernando Abilleira wrote:> Dear sourceforge community,> > I come from a Matlab environment so I am used to plotting matrices that > contain NaN elements. This is very useful because in some cases one > doesn't have data for the entire matrix. If one tries plotting the data, > the NaN elements won't be plotted.

Re: Python in Excel - 0 views

  • You can use Microsoft Script Control. If you have the win32 extensions of python, you can use python in place of vb in this control -open the VBA script editor - In menus/Tools/References add Microsoft Script Control -Make a new module and declare a new MsScriptControl.ScriptControl Global sc as new MsScriptControl.ScriptControl -Initialize the language attibute with python - Note that you and users of your document must have python and its win32 extensions installed. Activestate python distribustion include it. You can put sc.language="python" in the routine Workbook_Open() Now you can import python modules using ExecuteStatement method of the control in vba and have results from python functions with eval method. One interesting thing is that you can pass an object to the control with AddObject method and have python manipulate it. And so on..
  • Global sc As New MSScriptControl.ScriptControl Public Function os_getcwd() sc.Language = "python" sc.ExecuteStatement ("import os") os_getcwd = sc.Eval("os.getcwd()") End Function With this you can set your Excel formula to =os_getcwd() For me it returns "C:\Documents and Settings\Administrator\My Documents", which I needed to know at the time so I didn't have to screw around with the ever annoying pythonpath. You can put the first two lines of the function in the Workbook_Open hook, but I don't know where that is. I hope to use more Python in Excel soon. Hmm, actually, I suppose you can put those first two lines of the function after the Global declaration as well. I know just about zero VBScript and didn't get a chance to do anything else beyond proof of concept yet. I figured I would write something dynamic which allowed more transparent access to Python, maybe allowing formula like =py("os.getcwd()"), etc.

difference between classmethod and staticmethod in Python2.2 - 0 views

  • Use a staticmethod when you know which class you want to access as you are writing the code.
  • Use a classmethod if you have a class hierarchy and want the method to operate on the actual class used in the call rather than the class where it was defined:

Applying sympy expressions on numpy arrays - sympy | Google Groups - 0 views

  • If I have:     from sympy import Symbol, Integrate     x = Symbol('x')     f = x**2 + x     g = Integrate(f, x) how can I apply g to a numpy array? In other words, how can I "numpify" the g expression, injecting in it x = numpy.linspace(1, 9, 9)? What would be even nicer would be to be able to retrieve a lambda using numpy functions for g as a function of x (that way I don't have the overhead of numpifying it each time I want to apply it to an array).

ONLamp.com -- Introduction to Stackless Python - 0 views

  • Stackless Python is an alternative implementation of Python created by independent developer Christian Tismer. He started with the conventional Python language processor managed by the language's inventor, Guido van Rossum, and patched his own Stackless invention in place of a small but central part of Python's internals. Stackless Python is the result. This article introduces Tismer's technology and its significance. In future articles, you'll be able to read about how to make your own start at programming Stackless Python, as well as the prospects for a merger between Stackless and the main Python distribution.

pyscripter - Google Code - 0 views

  • PyScripter is a free and open-source Python Integrated Development Environment (IDE) created with the ambition to become competitive in functionality with commercial Windows-based IDEs available for other languages. Being built in a compiled language is rather snappier than some of the other Python IDEs and provides an extensive blend of features that make it a productive Python development environment.

Python Cookbook : Read tabular data from Excel spreadsheets the fast and easy way - 0 views

  • Sometimes you get an Excel spreadsheet (say, from the marketing departement) and you want to read tabular data from it (i.e. a line with column headers and lines of data). There are many ways to do this (including ODBC + mxODBC), but the easiest way I've found is this one : provide a file name and a sheet name, and read the data !

    Since learning JavaScript over a year ago, it's become one of my favorite dynamic programming languages alongside Python. And as I've mentioned before, I think the two languages actually complement each other pretty well.

scipy cluster example dendogram - 1 views

  • Now that we have a dendrogram from which to inspect, let's find a suitable color threshold. One can see roughly three major clusters formed by using a distance threshold of 1.2. Now, let's plot another dendrogram using this as the color threshold. The legend displays the predictions of each flat cluster formed by cutting with this threshold

Eli Bendersky's website » Python metaclasses by example - 12 views

    • Mauro De Giorgi
       
      Start read from here
  • Study and understand this example and you’ll grasp most of what one needs to know about writing metaclasses.
  • To control the creation and initialization of the class in the metaclass, you can implement the metaclass’s __new__ method and/or __init__ constructor [6]. Most real-life metaclasses will probably override just one of them. __new__ should be implemented when you want to control the creation of a new object (class in our case), and __init__ should be implemented when you want to control the initialization of the new object after it has been created.
  • ...3 more annotations...
  • It’s important to note here that these print-outs are actually done at class creation time, i.e. when the module containing the class is being imported for the first time. Keep this detail in mind for later.
  • So when the call to MyMeta is done above, what happens under the hood is this:
