SQLAlchemy - The Database Toolkit for Python

SQLAlchemy - The Database Toolkit for Python
SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language. SQL databases behave less like object collections the more size and performance start to matter; object collections behave less like tables and rows the more abstraction starts to matter. SQLAlchemy aims to accommodate both of these principles. SQLAlchemy considers the database to be a relational algebra engine, not just a collection of tables. Rows can be selected from not only tables but also joins and other select statements; any of these units can be composed into a larger structure.

6 Free E-Books on Learning to Program with Python Python is an increasingly popular language, and it's also a favorite language teaching first time programmers. We've compiled a list of beginner's books to choose from. Just because they're free doesn't mean they aren't good. Toad - SQL Tuning, Database Development & Administration Software Oracle Toad simplifies the manual, time-intensive tasks associated with Oracle development, administration, performance management, and querying and reporting. It provides Oracle-specific capabilities that enable you to meet SLAs with ease. Plus, Toad can help you with change, configuration, and release management. SQL Server Ensuring good SQL Server performance is demanding work.

Learn Python This exercise has no code. It is simply the exercise you complete to get your computer to run Python. You should follow these instructions as exactly as possible. For example, Mac OS X computers already have Python 2, so do not install Python 3 (or any Python). Go to with your browser, get the Notepad++ text editor, and install it. You do not need to be the administrator to do this.Make sure you can get to Notepad++ easily by putting it on your desktop and/or in Quick Launch.

Easy data modeling with PyModels — PyModels v0.18 documentation PyModels is a lightweight framework for mapping Python classes to schema-less databases. It is not an ORM as it doesn’t map existing schemata to Python objects. Instead, it lets you define schemata on a higher layer built upon a schema-less storage (key/value or document-oriented). You define models as a valuable subset of the whole database and work with only certain parts of existing entities – the parts you need. Topics:

Python for Fun This collection is a presentation of several small Python programs. They are aimed at intermediate programmers; people who have studied Python and are fairly comfortable with basic recursion and object oriented techniques. Each program is very short, never more than a couple of pages and accompanied with a write-up. I have found Python to be an excellent language to express algorithms clearly.

s Python Class - Google for Education 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. The first exercises work on basic Python concepts like strings and lists, building up to the later exercises which are full programs dealing with text files, processes, and http connections. The class is geared for people who have a little bit of programming experience in some language, enough to know what a "variable" or "if statement" is. Beyond that, you do not need to be an expert programmer to use this material.

Fast, Easy Database Access with Python ave you ever found it tedious to mix SQL and other languages, or been reluctant to write the same four lines of code again to do a simple database query? This article can help you eliminate the drudgery involved in database access, and make your programming time more efficient, by wrapping simple transactions in friendly native Python syntax. By making the database emulate regular Python objects, you can remove a source of friction and frustration from your development process. Your time spent programming will be more efficient and productive when you can focus on the task at hand, without being constantly sidetracked by unimportant details like where the cursor object is, or whether you need to escape-protect the data in the next query. Another benefit of using native syntax is better portability.

How to make beautiful data visualizations in Python with matplotlib It’s been well over a year since I wrote my last tutorial, so I figure I’m overdue. This time, I’m going to focus on how you can make beautiful data visualizations in Python with matplotlib. There are already tons of tutorials on how to make basic plots in matplotlib. There’s even a huge example plot gallery right on the matplotlib web site, so I’m not going to bother covering the basics here. However, one aspect that’s missing in all of these tutorials and examples is how to make a nice-looking plot.
