YQafj.png (773×938) PyBrain. 10 Reasons Python Rocks for Research — Hoyt Koepke. The following is an account of my own experience with Python. Because that experience has been so positive, it is an unabashed attempt to promote the use of Python for general scientific research and development. About four years ago, I dropped MATLAB in favor of Python as my primary language for coding research projects.
This article is a personal account of how rewarding I have found that experience. As I describe in the next sections, the variety and quality of Python’s features has spoiled me. To clarify, I am not advocating just Python as the perfect scientific programming environment; I am advocating Python plus a handful of mature 3rd-party open source libraries, namely Numpy/Scipy for numerical operations, Cython for low-level optimization, IPython for interactive work, and MatPlotLib for plotting. Holistic Language Design I once believed that the perfect language for research was one that allowed concise and direct translation from notepad scribblings to code.
Readability gives. 1. An Introduction to Distutils — Python v2.7 documentation. This document covers using the Distutils to distribute your Python modules, concentrating on the role of developer/distributor: if you’re looking for information on installing Python modules, you should refer to the Installing Python Modules chapter. 1.1. Concepts & Terminology Using the Distutils is quite simple, both for module developers and for users/administrators installing third-party modules.
As a developer, your responsibilities (apart from writing solid, well-documented and well-tested code, of course!) Are: write a setup script (setup.py by convention)(optional) write a setup configuration filecreate a source distribution(optional) create one or more built (binary) distributions Each of these tasks is covered in this document. Not all module developers have access to a multitude of platforms, so it’s not always feasible to expect them to create a multitude of built distributions. 1.2.

As I describe in the next sections, the variety and quality of Python’s features has spoiled me. Even in small scripts, I now rely on Python’s numerous data structures, classes, nested functions, iterators, the flexible function calling syntax, an extensive kitchen-sink-included standard library, great scientific libraries, and outstanding documentation. Given these libraries, many features in MATLAB that enable one to quickly write code for machine learning and artificial intelligence – my primary area of research – are essentially a small subset of those found in Python.

Get started with Installation and then get an overview with the Quickstart. There is also a more detailed Tutorial that shows how to create a small but complete application with Flask. Common patterns are described in the Patterns for Flask section. The rest of the docs describe each component of Flask in detail, with a full reference in the API section. Flask depends on the Werkzeug WSGI toolkit, the Jinja template engine, and the Click CLI toolkit. User’s Guide¶ Flask provides configuration and conventions, with sensible defaults, to get started. API Reference¶ If you are looking for information on a specific function, class or method, this part of the documentation is for you.

Optimizing compiler for evaluating mathematical expressions on CPUs and GPUs. Latest Version: 0.6.0 Theano is a Python library that allows you to define, optimize, and efficiently evaluate mathematical expressions involving multi-dimensional arrays. It is built on top of NumPy. Theano features: tight integration with NumPy: a similar interface to NumPy's. numpy.ndarrays are also used internally in Theano-compiled functions.transparent use of a GPU: perform data-intensive computations up to 140x faster than on a CPU (support for float32 only).efficient symbolic differentiation: Theano can compute derivatives for functions of one or many inputs.speed and stability optimizations: avoid nasty bugs when computing expressions such as log(1+ exp(x) ) for large values of x.dynamic C code generation: evaluate expressions faster.extensive unit-testing and self-verification: includes tools for detecting and diagnosing bugs and/or potential problems.
John Anderson ( sontek ) - Debugging Python with pdb. Being a great debugger is almost as important as being great at writing the software. I think I spend just as much time debugging programs as I do writing them. pdb (python debugger) is a very powerful tool for interactively debugging the state of your application and inspecting portions of your code. For the rest of this post we are going to be debugging a file called fib.py with the following code: # fib.pydef main(): low = 0 high = 1 for i in range(10): print high new_high = get_new_high(low, high) low = high high = new_high def get_new_high(low, high): return low + high if __name__ == '__main__': main() There are many ways to get your application to drop into pdb, the first way is to import pdb in the file you want to debug and put pdb.set_trace() on any lines you want to debug.
So we are going to change our file to look like this: You will see it shows you what method its in and the next line its going to run: python fib.py> /home/sontek/code/test/fib.py(3)main()-> low = 0. Features of the Standard Library.
