• Unifying types and classes in Python 2.2

  ...function argument in a special kind of descriptor whose __get__() method returns the original function unchanged. More on __get__ methods: in Python 2.2, the magic of binding methods to instances (even for classic classes!) is done through the __get__ method of the object found in the class. The __get__ method for regular function objects returns a bound method object; the __get__ method for staticfunction objects returns the underlying function. If a class attribute has no __get__ m...

  ...definition of the save method would mean that a D instance, when requested to save itself, only saves the A and B parts of its data, but not the part of its data defined by class C! C++ notices that D inherits two conflicting definitions of method m, and issues an error message. The author of D is then supposed to override m to resolve the conflict. But what is D's definition of m supposed to do? It can call B's m followed by C's m, but because both definitions call the definition of...

• Towards a Standard Parser Generator

  ...function is invoked to return the next token. Token numbers identify tokens. In addition, the yylval variable carries the semantic value. Older versions of BisonGen generate flex files from token definitions given XML; the recent versions generate re-style regular expressions from similar XML specifications. Error handling also follows the YACC tradition: an yyerror function is invoked. Since unwinding out of a bison parser run is not easy, this function normally only sets a global...

A JavaScript 'tracking code' is installed on client web pages and provides the server with active web analytics. Some of the other technologies we're using at the moment for WordStream are Adobe Flex, Linux, Apache, and C/C++. As for development process tools, we're using PyDev Extensions, Trac, Buildbot, Review Board, and Git. The Decision to Use Python Python was used from the start of th...

  ...function or class, but is not local, the definition in the nearest enclosing function scope will be used. One consequence of this change is that lambda statements could reference variables in the namespaces where the lambda is defined. In some unusual cases, this change will break code. In all previous version of Python, names were resolved in exactly three namespaces -- the local namespace, the global namespace, and the builtin namespace. According to this old definition, if a function A is ...

• Standard Exception Classes in Python 1.5

  ...Functions Two new intrinsic functions for class testing were introduced (since the functionality had to be implemented in the C API, there was no reason not to make it accessible to Python programmers). issubclass(D, C) returns true iff class D is derived from class C, directly or indirectly. issubclass(C, C) always returns true. Both arguments must be class objects. isinstance(x, C) returns true iff x is an instance of C or of a (direct or indirect) subclass of C. The fi...

The Python web site provides a Python Package Index (also known as the Cheese Shop, a reference to the Monty Python script of that name). There is also a search page for a number of sources of Python-related information. Failing that, just Google for a phrase including the word ''python'' and you may well get the result you need. If all else fails, ask on the python newsgroup and there's a good chance so...

  ...function _PyTime_DoubleToTimet added, to convert a Python timestamp (C double) to platform time_t with some out-of-bounds checking. Declared in new header file timefuncs.h. It would be good to expose some other internal timemodule.c functions there. New public functions PyEval_EvaluateFrame and PyGen_New to expose generator objects. New public functions Py_IncRef() and Py_DecRef(), exposing the functionality of the Py_XINCREF() and Py_XDECREF macros. Useful for runtime dynamic embedding of Pyt...
