PyXLL: Deploy Python to Excel Easily. PyXLL Solution Home | Download PyXLL | Press Release Today Enthought announced that it is now the worldwide distributor for PyXLL, and we’re excited to offer this key product for deploying Python models, algorithms and code to Excel.

PyXLL: Deploy Python to Excel Easily

Technical teams can use the full power of Enthought Canopy, or another Python distro, and end-users can access the results in their familiar Excel environment. And it’s pretty straightforward to set up and use. PyXLL is free for non-commercial and evaluation purposes, and in Canopy you can simply grab it from the Enthought repo via the Package Manager as shown in the screenshots below (note that at this time PyXLL is only available for Windows users). The rest of the configuration instructions are in the Quick Start portion of the documentation. To create a PyXLL Python Excel function, you use the @xl_func decorator to tell PyXLL the following function should be registered with Excel, what its argument types are, and optionally what its return type is.

Distributed parallel programming in Python : MPI4PY. 1 Introduction MPI stands for Message passing interface.

Distributed parallel programming in Python : MPI4PY

An implementation of MPI such as MPICH" or OpenMPI is used to create a platform to write parallel programs in a distributed system such as a Linux cluster with distributed memory. Generally the platform built allows programming in C using the MPI standard. So in order to run Parallel programs in this environment in python, we need to make use of a module called MPI4py which means "MPI for Python". This module provides standard functions to do tasks such as get the rank of processors, send and receive messages/ data from various nodes in the clusters. Once MPI4PY is installed, you can start programming in it. 2 Sending and receiving Messages Communication in mpi4py is done using the send() and he recv() methods. 2.1 Introduction to send() The general syntax of this function is: comm.send(data,dest) here "data" can be any data/message which has to be sent to another node and "dest" indicates the process rank of node(s) to send it to.

It allows developers to work efficiently and forget about the boilerplate. While some programmers scoff at the idea of using anything more than a text editor, when you are working on a very big project consisting of many files, an IDE will have features that will make your life as a developer much easier. Some features you can expect a good IDE to have are: Code completionSyntax highlightingTemplates for common codeSource Control support (eg. Subversion, Mercurial or Git) Let's see which Python IDE's are the best and how they stack up against each other. Eclipse with PyDev PyDev's Official Site: Eclipse is a very versatile IDE that's been around for a very long time.

It's a completely free IDE that offer a wide array of features such as: I use this when coding in Python on my Windows machine, it just works with minimal configuration.

Introduction One thing that you will get to know about programming, is that programmers like to be lazy.

Lesson 8 - Classes

If something has been done before, why should you do it again? That is what functions cover in python. You've already had your code do something special. Now you want to do it again. Of course, functions have their limitations. That can easily be worked around with normal functions. Chances are that you also have more than one golf club. Or what if you want a golf club, which has added extra features? These problems that a thing called object-oriented-programming solves. Creating a Class What is a class? So how do you make these so-called 'classes'? Code Example 1 - defining a class # Defining a class class class_name: [statement 1] [statement 2] [statement 3] [etc] Makes little sense?

Code Example 2 - Example of a Class What you have created is a description of a shape (That is, the variables) and what operations you can do with the shape (That is, the fuctions).
