#Python library reference 2.7 manual#
This library reference manual documents Python’s standard library, as well as many optional library modules (which may or may not be available, depending on whether the underlying platform supports them and on the conguration choices made at compile time). For example, to find the length of the third item of the list menInTub, type len(menInTub). encourage and enhance the portability of Python programs. However, to find the length in characters of one of those given strings within your list, include its position number.

SQLAlchemy's overall approach to these problems is entirely differentįrom that of most other SQL / ORM tools, rooted in a so-called complimentarity. SQLAlchemy is most famous for its object-relational mapper (ORM), an optionalĬomponent that provides the data mapper pattern, whereĬlasses can be mapped to the database in open ended, multiple ways -Īllowing the object model and database schema to develop in a cleanly Language builds on this concept from its core. Units can be composed into a larger structure. Tables but also joins and other select statements any of these SQLAlchemy considers the database to be a relational algebra engine, Tables and rows the more abstraction starts to matter. Size and performance start to matter object collections behave less like SQL databases behave less like object collections the more Into a simple and Pythonic domain language.
