Python Cost Model - 6.006 Wiki From 6.006 Wiki Python is a high-level programming language, with many powerful primitives. Analyzing the running time of a Python program requires an understanding of the cost of the various Python primitives. For example, in Python, you can write: where L, L1, and L2 are lists; the given statement computes L as the concatenation of the two input lists L1 and L2. Our goal in this section is to review various Python primitive operations, and to determine bounds and/or estimates on their running times. The Python implementation code base is here. Python Running Time Experiments and Discussion The running times for various-sized inputs were measured, and then a least-squares fit was used to find the coefficient for the high-order term in the running time. The least-squares fit was designed to minimize the sum of squares of relative error, using scipy.optimize.leastsq. The machine used was an IBM Thinkpad T43p with a 1.86GHz Pentium M processor and 1.5GB RAM. Cost of Python Integer Operations
Google's Python Class - Educational Materials Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python. The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. To get started, the Python sections are linked at the left -- Python Set Up to get Python installed on your machine, Python Introduction for an introduction to the language, and then Python Strings starts the coding material, leading to the first exercise. This material was created by Nick Parlante working in the engEDU group at Google. Tip: Check out the Python Google Code University Forum to ask and answer questions.
25 Facts About BDSM That You Won't Learn In "Fifty Shades Of Grey" Google Python Style Guide No whitespace inside parentheses, brackets or braces. No whitespace before a comma, semicolon, or colon. Do use whitespace after a comma, semicolon, or colon except at the end of the line. Yes: if x == 4: print x, y x, y = y, x No: if x == 4 : print x , y x , y = y , x No whitespace before the open paren/bracket that starts an argument list, indexing or slicing. Yes: dict['key'] = list[index] No: dict ['key'] = list [index] Surround binary operators with a single space on either side for assignment (=), comparisons (==, <, >, ! Don't use spaces around the '=' sign when used to indicate a keyword argument or a default parameter value. Yes: def complex(real, imag=0.0): return magic(r=real, i=imag) No: def complex(real, imag = 0.0): return magic(r = real, i = imag) Don't use spaces to vertically align tokens on consecutive lines, since it becomes a maintenance burden (applies to :, #, =, etc
Python Weekly: A Free, Weekly Python E-mail Newsletter MATLAB Tutorial MATLAB is a programming language developed by MathWorks. It started out as a matrix programming language where linear algebra programming was simple. It can be run both under interactive sessions and as a batch job. This tutorial gives you aggressively a gentle introduction of MATLAB programming language. This tutorial has been prepared for the beginners to help them understand basic to advanced functionality of MATLAB. We assume you have a little knowledge of any computer programming and understand concepts like variables, constants, expression, statements, etc. For most of the examples given in this tutorial you will find Try it option, so just make use of it and enjoy your learning. Try following example using Try it option available at the top right corner of the below sample code box:

In the tutorial I presented at PyCon 2006 (called Text & Data Processing), I was surprised at the reaction to some techniques I used that I had thought were common knowledge. Many of you will have seen some of these techniques and idioms before. These are the guiding principles of Python, but are open to interpretation. import this
Python's IDLE editor: How to Use - by Dr A. Dawson Copyright Dr A Dawson 2005 - 2016 This file is: Python_Editor_IDLE.htm First created: Tuesday 8th March 2005, 7:28 PT, ADLast updated: Saturday 31st January 2015, 9:05 PT, AD This page explains how to run the IDLE integrated development environment (IDE) for editing and running Python 2.x or Python 3 programs. The IDLE GUI (graphical user interface) is automatically installed with the Python interpreter. IDLE was designed specifically for use with Python. Watch the IDLE Editor movie below (11 minutes)... Python Editor IDLE movie Notice that with syntax highlighting, Python keywords, comments, literal text etc are displayed in different colours or fonts, which makes it much easier for programmers to find errors in their program code. Which version of Python should you install? More Python Resources Follow these instructions to write and run a simple Python program using the IDLE editor: 1. 2. 4. 5. 8. 10.
