A talk for the SciPy 2006 Conference by Andrew Straw. Commodity computers continue to become ever faster, through increases in clock speed and now through addition of multiple processor cores. The ability to use these resources in a closed-loop scientific or engineering task enables new types of applications with greatly reduced needs on specialized software and hardware.
Python is more popular than ever, and is being used everywhere from back-end web servers, to front-end game development, and everything in between.
Description The method strptime() parses a string representing a time according to a format.
Any code that you write using any compiled language like C, C++ or Java can be integrated or imported into another Python script. This code is considered as an "extension".
In the previous post we have seen how to compute the fft of a one dimensional signal . In this post we will see how to compute and plot the Fourier spectrum of an image (we can think at images as a bidimensional signals) and how to use the spectrum in order to make an high pass filter in the frequency domain. The following function implements an high pass filter in three steps: computes the frequency spectrum cuts the low frequencies from the spectrum and finally, the filtered time domain signal is calculated from the modified frequency spectrum
Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.
This is a hands-on primer which has a little bit of beginner instructions along with more advanced topics. Feel free to skip over the first four units if you are already comfortable with your basic knowledge of Python.
NOTE: If you would like some Python development done, my company, Stochastic Technologies , is available for consulting.
Programming is great.
In this interactive tutorial, we'll cover many essential Python idioms and techniques in depth, adding immediately useful tools to your belt. There are 3 versions of this presentation: ©2006-2008, licensed under a Creative Commons Attribution/Share-Alike (BY-SA) license .
The intent of this page is to list some of the most commonly used Python modules, in the hope that it will provide useful recommendations for other programmers (especially beginners). Remember that in addition to the listings below, there are other directories of Python modules - see PublishingPythonModules for details. Another collection of library details can be found on the Libraries page.
There’s a handy 3rd party module called pyPdf out there that you can use to merge PDFs documents together, rotate pages, split and crop pages, and decrypt/encrypt PDF documents. In this article, we’ll take a look at a few of these functions and then create a simple GUI with wxPython that will allow us to merge a couple of PDFs.
The following sections describe the standard types that are built into the interpreter.
