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.
How to Think Like a Computer Scientist — How to Think Like a Computer Scientist: Learning with Python 2nd Edition documentation Navigation How to Think Like a Computer Scientist¶ Learning with Python¶ What coding class should I take: Programming is like learning a new language. Illustration by Mouni Feddag “You don’t need to go to grad school. Save your money. I’ll teach you how to code.” Seven years ago, in a bar near downtown Los Angeles, I was sharing a drink with a new friend. We had met on a travel website and he had just finished giving me some excellent advice about Southeast Asia, where I was heading for a month.
GPIO Examples 1 - A single LED Before we even get started with the GPIO, lets make an LED light up by simply wiring it to the +3.3v supply and 0v. Single LED Lit up One LED on the 3.3v supply So… We have a yellow wire from the Pi’s +3.3v supply to the breadboard and this connects to an LED then via a 270Ω (ohm) resistor to 0v. The green wire connects back to the Pi. 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.
Python: Inverted Index for dummies An Inverted Index is an index data structure storing a mapping from content, such as words or numbers, to its document locations and is generally used to allow fast full text searches. The first step of Inverted Index creation is Document Processing In our case is word_index() that consist of word_split(), normalization and the deletion of stop words ("the", "then", "that"...). def word_split(text): word_list =  wcurrent =  windex = None for i, c in enumerate(text): if c.isalnum(): wcurrent.append(c) windex = i elif wcurrent: word = u''.join(wcurrent) word_list.append((windex - len(word) + 1, word)) wcurrent =  if wcurrent: word = u''.join(wcurrent) word_list.append((windex - len(word) + 1, word)) return word_list word_split() is quite a long function that does a really simple job split words.
Computer Science Circles Variables act as "storage locations" for data in a program. They are a way of naming information for later usage. Each variable has a name; an example variable name we will use is myLuckyNumber. To store information in a variable, we write a command using an equal sign in the following way:
Design Methods Step 1: Discover This four-part guide is for anyone who wants to understand the methods designers use and try them out for themselves. We’ve grouped 25 design methods into four steps – Discover, Define, Develop and Deliver – based on the stages of the Double Diamond, the Design Council’s simple way of mapping the design process From rapid prototyping to personas and surveys, methods like these are used all the time in our work with partners. Browse through our case studies to see how they have been instrumental in bringing about dramatic improvements to products, services and environments, ensuring they are clearly focused on the needs of users. Use the methods below to keep your perspectives wide, allowing for a broad range of ideas and influences. Adding a Bluetooth serial terminal to Raspberry Pi Sometimes you find a computer component that’s so cheap, that works so well, that you’re amazed you managed to live without it for so long. The JY-MCU Arduino Bluetooth Wireless Serial Port Module is that component for me right now. JY-MCU Arduino Bluetooth Wireless Serial Port Module from dx.com This little board is a cheap ($8.50!)
