  • Python Success Stories

    ...program structure was a stumbling block during this initial contact and Python was not adopted for use with that project. On second look, after actual experience with the language, the language's indentation-defined structure became a virtue, an important part of the overall power and simplicity of the language. In addition to Python's clean design, the following factors make Python a good choice for enterprise integration tasks, like those undertaken at Gusto.com: OS Independence - The ability...

  • Towards a Standard Parser Generator

    ...program. The generated parsers need to support parsing of Unicode strings. Although this requirement is specific to XPath, Unicode support is desirable whenever the input may come in different encodings. In addition, the following non-critical criteria are used for ranking the parsers: Since the XSL Transformations [W3C99a] are a primary application for XPath expressions, and since many short expressions occur in a typical XSLT style sheet, it is desirable...

    ...programs (for example, ZoneAlarm) open a dialog of their own when any program opens a socket. IDLE does use sockets, talking on the computer's internal loopback interface. This connection is not visible on any external interface and no data is sent to or received from the Internet. So, if you get such a dialog when opening IDLE, asking whether to let pythonw.exe talk to address 127.0.0.1, say yes, and rest assured no communication external to your machine is taking place.

It could be argued that NameError and AttributeError should be derived from LookupError, but this is questionable and depends entirely on the application. Exception Class Definitions The Python class definitions for the standard exceptions are imported from the standard module "exceptions". You can't change this file thinking that the changes will automatically show up in the standa...

    ...programmers (especially if there are several hundreds of lines of code between the reference and the assignment to x :-). You can now override the 'in' operator by defining a __contains__ method. Note that it has its arguments backwards: x in a causes a.__contains__(x) to be called. That's why the name isn't __in__. The exception AttributeError will have a more friendly error message, e.g.: 'Spam' instance has no attribute 'eggs'. This may break code that expects the message to be...
