Essential SQLAlchemy

Essential SQLAlchemy introduces a high-level open-source code library that makes it more uncomplicated for Python programmers to entry relational databases equivalent to Oracle, DB2, MySQL, PostgreSQL, and SQLite. SQLAlchemy has develop into more and more renowned seeing that its unlock, however it nonetheless lacks sturdy offline documentation. This useful ebook fills the space, and since a developer wrote it, you get an goal examine SQLAlchemy's instruments instead of an advocate's description of the entire "cool" features.

SQLAlchemy comprises either a database server-independent SQL expression language and an object-relational mapper (ORM) that allows you to map "plain outdated Python objects" (POPOs) to database tables with out considerably altering your present Python code. crucial SQLAlchemy demonstrates the way to use the library to create an easy database software, walks you thru basic queries, and explains the right way to use SQLAlchemy to hook up with a number of databases at the same time with an identical Metadata. you furthermore mght find out how to:

* Create customized forms for use on your schema, and while it's worthy to exploit customized instead of integrated kinds
* Run queries, updates, and deletes with SQLAlchemy's SQL expression language
* construct an item mapper with SQLAlchemy, and comprehend the variations among this and lively checklist styles utilized in different ORMs
* Create items, retailer them to a consultation, and flush them to the database
* Use SQLAlchemy to version item orientated inheritance
* offer a declarative, energetic list development to be used with SQLAlchemy utilizing the Elixir extension
* Use the SQLSoup extension to supply an automated metadata and item version in keeping with database mirrored image

In addition, you'll find out how and while to take advantage of different extensions to SQLAlchemy, together with AssociationProxy, OrderingList, and more.

Essential SQLAlchemy is the much-needed advisor for each Python developer utilizing this code library. rather than a feature-by-feature documentation, this publication takes an "essentials" technique that provides you precisely what you must turn into efficient with SQLAlchemy correct away.

Mastering Regular Expressions (3rd Edition)

Regular expressions are an incredibly strong instrument for manipulating textual content and knowledge. they're now general positive factors in quite a lot of languages and well known instruments, together with Perl, Python, Ruby, Java, VB. web and C# (and any language utilizing the . web Framework), Hypertext Preprocessor, and MySQL.

when you don't use general expressions but, you'll find during this ebook an entire new global of mastery over your facts. should you already use them, you'll savor this book's unheard of aspect and breadth of insurance. should you imagine you recognize all you must learn about general expressions, this ebook is a gorgeous eye-opener.

As this e-book exhibits, a command of normal expressions is a useful ability. commonplace expressions let you code advanced and refined textual content processing that you simply by no means imagined may be computerized. average expressions can prevent time and aggravation. they are often used to craft based suggestions to a variety of difficulties. as soon as you've mastered general expressions, they'll turn into a useful a part of your toolkit. you'll ask yourself the way you ever obtained by means of with out them.

but regardless of their extensive availability, flexibility, and unprecedented energy, ordinary expressions are usually underutilized. but what's energy within the fingers of a professional should be fraught with peril for the unwary. gaining knowledge of normal Expressions can assist you navigate the minefield to changing into a professional and assist you optimize your use of normal expressions.

gaining knowledge of average Expressions, 3rd variation, now encompasses a complete bankruptcy dedicated to Hypertext Preprocessor and its strong and expressive suite of normal expression services, as well as more desirable Hypertext Preprocessor assurance within the principal "core" chapters. moreover, this variation has been up to date all through to mirror advances in different languages, together with increased in-depth assurance of Sun's java. util. regex package deal, which has emerged because the usual Java regex implementation. subject matters include:
* A comparability of gains between varied models of many languages and instruments
* How the ordinary expression engine works
* Optimization (major reductions to be had right here! )
* Matching simply what you will have, yet now not what you don't wish
* Sections and chapters on person languages

Written within the lucid, unique tone that makes a fancy, dry subject develop into crystal-clear to programmers, and sprinkled with suggestions to advanced real-world difficulties, gaining knowledge of typical Expressions, 3rd version bargains a wealth details that you should positioned to fast use.

Reviews of this re-creation and the second one edition:

"There isn't a greater (or extra helpful) publication on hand on ordinary expressions. "

--Zak Greant, dealing with Director, eZ Systems

"A actual tour-de-force of a booklet which not just covers the mechanics of regexes in remarkable element but additionally talks approximately potency and using regexes in Perl, Java, and . internet. .. in the event you use normal expressions as a part of your expert paintings (even in case you have already got a superb ebook on no matter what language you're programming in) i might strongly suggest this e-book to you. "

--Dr. Chris Brown, Linux Format

"The writer does a superb activity major the reader from regex beginner to grasp. The booklet is very effortless to learn and chock packed with important and proper examples. .. commonplace expressions are priceless instruments that each developer must have of their toolbox. studying ordinary Expressions is the definitive advisor to the topic, and an exceptional source that belongs on each programmer's bookshelf. Ten out of Ten Horseshoes. "

Sample text

Such numbers consist of two parts: digits and an exponent. The exponent is adjusted so the decimal point “floats” to just after the first digit (or just before, depending on the implementation), as in scientific notation. 5 You might occasionally see floats represented in a form of scientific notation, with the letter “e” separating the base from the exponent. When Python prints a number in scientific notation it will always have a single digit before the decimal point, some number of digits following the decimal point, a + or - following the e, and finally an integer.

Within the range of ordinary floats # so printed as an ordinary float. # An innocent-looking float that is # smaller than the lower limit, so e. # A float with many digits that is # smaller than the upper limit, so no e. # Finally, a float that is larger than the # upper limit, so printed with an e. Simple Values | 3 Strings Strings are series of Unicode* characters. Their type is str. Many languages have a separate “character” type, but Python does not: a lone character is simply a string of length one.

STATEMENT Two-Expression Assertion A two-expression assertion statement takes two arguments: an expression to evaluate and an expression to use in the error report if the first expression is false. assert expression1, expression2 Example 2-9 shows a two-expression assertion. Example 2-9. A failed assertion with a second expression >>> assert 1 == 2, 'invalid arguments' Traceback (most recent call last): File "", line 1, in assert 1 == 2, "invalid arguments" AssertionError: invalid argument Let’s improve gc_content by ensuring that its argument is a valid sequence string.
