    ...strings encoded in the preferred encoding, as informed by locale module's getpreferredencoding(). optparse module (and tests) upgraded to Optik 1.5a1. Changes: Add expansion of default values in help text: the string "%default" in an option's help string is expanded to str() of that option's default value, or "none" if no default value. Bug #955889: option default values that happen to be strings are now processed in the same way as values from the command line; this allow...

    ...string operations, as well as a number of other changes to improve performance. New language features Internally, the Python compiler now converts the source code to an abstract syntax tree (AST) before producing the bytecode. The 'with' operator replaces a common try/finally idiom that results in much cleaner and safer code. Generators gained send, throw and close methods. Values passed to send will be returned by the yield statement when the generator is resumed. throw takes an exception and...

  • Debugging Reference Count Problems

    ...String_AsString(PyObject_Repr(env))); This creates a new string object that is never collected: the new string object returned by PyObject_Repr(). Since this is presumably a big string and you are allocating a lot of them (one each time you get to this print statement) the malloc pattern of your application becomes very different and this means that you may see very different behavior. So, (maybe from shock), I eliminate the Py_INCREFs and try with just the printing... still...

    ...string argument. Previously, this constructor ignored its arguments. As a consequence, deriving a class from a module (not from the module type) is now illegal; previously this created an unnamed module, just like invoking the module type did. [SF bug 563060] A new type object, 'basestring', is added. This is a common base type for 'str' and 'unicode', and can be used instead of types.StringTypes, e.g. to test whether something is "a string": isinstance(x, basestring) is True for Un...
