Portable Python Looking for the best solutions :: CHECKIO.ORG Dive Into Python Getting a grip on Python: six ways to learn online Recently, Google has stepped up its presence in the cloud computing arena. Google's new App Engine (aka "AppSpot") lets you design and run web applications using Google's existing infrastructure. Their (free) basic account offers up to half a gigabyte of storage plus the computing power to push approximately 5 million page views per month. App Engine applications run in secure sandboxes that distribute application load across multiple servers. Python only At this time, App Engine uses Python as its primary programming language.

For Beginners Welcome! Are you completely new to programming? If not then we presume you will be looking for information about why and how to get started with Python. Installing Python is generally easy, and nowadays many Linux and UNIX distributions include a recent Python. If you want to know whether a particular application, or a library with particular functionality, is available in Python there are a number of possible sources of information. If you have a question, it's a good idea to try the FAQ, which answers the most commonly asked questions about Python. If you want to help to develop Python, take a look at the developer area for further information.
Python for Software Design: How to Think Like a Computer Scientist How to Think Like a Computer Scientist by Allen B. Downey This is the first edition of Think Python. Buy this book at Amazon.com Download Think Python in PDF. Read Think Python in HTML. Example programs and solutions to some problems are here (links to specific examples are in the book). Description Think Python is an introduction to Python programming for beginners. Some examples and exercises are based on Swampy, a Python package written by the author to demonstrate aspects of software design, and to give readers a chance to experiment with simple graphics and animation. Think Python is a Free Book. If you have comments, corrections or suggestions, please send me email at feedback{at}thinkpython{dot}com.

ProgramacaoOrientadaObjetoPython - PythonBrasil 1. Introdução Este pequeno manual traduzido de Estrutura de Dados e Algoritmos com Padrões de Projetos Orientado a Objeto em Python de Bruno R. Preiss identifica e descreve as características da linguagem de programação Python. 2. Objetos e Tipos de dados Um objeto em linguagem de programação abstrata representa a posição onde será armazenada. * Tipo: O tipo de um objeto determina os valores que o objeto pode receber e as operações que podem ser executadas nesse objeto. * Valor: O valor de um objeto é o índice de memória ocupada por essa variável. * Tempo de vida: A vida de um objeto é o intervalo de tempo de execução de um programa em Python, é durante este tempo que o objeto existe. Python define uma extensa hierarquia de tipos. 3. A fim de utilizar um objeto em um programa em Python, esse objeto deve ter um nome. Veja: Esta indicação cría um objeto com nome i e liga vários atributos com esse objeto. Se nós seguirmos esta indicação com uma indicação de atribuição como: A comparação ficaria:
The "Invent with Python" Blog — Stop Using “print” for Debugging: A 5 Minute Quickstart Guide to Python’s logging Module This tutorial is short.To figure out bugs in your code, you might put in print statements/print() calls to display the value of variables.Don’t do this. Use the Python logging module. The logging is better than printing because: It’s easy to put a timestamp in each message, which is very handy.You can have different levels of urgency for messages, and filter out less urgent messages.When you want to later find/remove log messages, you won’t get them confused for real print() calls.If you just print to a log file, it’s easy to leave the log function calls in and just ignore them when you don’t need them. Using print is for coders with too much time on their hands. To print log messages to the screen, copy and paste this code: import logging logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s') logging.debug('This is a log message.') To write log messages to a file, you can copy and paste this code (the only difference is in bold):

The "Invent with Python" Blog — “How much math do I need to know to program?” Not That Much, Actually. Here are some posts I’ve seen on the r/learnprogramming subreddit forum: Math and programming have a somewhat misunderstood relationship. Many people think that you have to be good at math or made good grades in math class before you can even begin to learn programming. Not that much actually. For general programming, you should know the following: Addition, subtraction, division, and multiplication – And really, the computer will be doing the adding, subtracting, dividing, and multiplying for you anyway. Computers work with binary data, which is a number system with only two digits: 0 and 1. The numbers are still the exact same, but they are written out differently because there are a different number of digits in each system. See the Odometer Number Systems page in a new window. You don’t even have to know the math of converting a number from one number system to another. (On a side note, hexadecimal is used because one hexadecimal digit can represent exactly four binary digits.
ForLoop Usage in Python When do I use for loops? For loops are traditionally used when you have a piece of code which you want to repeat n number of times. For loop from 0 to 2, therefore running 3 times. for x in range(0, 3): print "We're on time %d" % (x) While loop from 1 to infinity, therefore running infinity times. x = 1 while True: print "To infinity and beyond! As you can see, they serve different purposes. How do they work? If you've done any programming before, there's no doubt you've come across a for loop or an equivalent to it. Nested loops When you have a piece of code you want to run x number of times, then code within that code which you want to run y number of times, you use what is known as a "nested loop". Early exits Like the while loop, the for loop can be made to exit before the given object is finished. Things to remember range vs xrange The range function creates a list containing numbers defined by the input. Examples Nested loops Early exit for x in xrange(3): if x == 1: break
