    ...reversed() builtin function that returns a reverse iterator over a sequence. Added a sorted() builtin function that returns a new sorted list from any iterable. CObjects are now mutable (on the C level) through PyCObject_SetVoidPtr. list.sort() now supports three keyword arguments: cmp, key, and reverse. The key argument can be a function of one argument that extracts a comparison key from the original record: mylist.sort(key=str.lower). The reverse argument is a boolean value and if True will...

  • Python Patterns - An Optimization Anecdote

    ...reverse operation? I.e. create a list of integer ASCII values from a string. Oh no, here we go again, it flashed through my mind... But this time, it was relatively painless. There are two candidates, the obvious: def g1(string): return map(ord, string) and the somewhat less obvious: import array def g2(string): return array.array('b', string).tolist() Timing these reveals that g2() is about five times as fast as g1(). There's a catch ...

  • What's new in Python 2.3

    ...reverses a string. None - assignment to variables or attributes named None will now trigger a warning. In the future, None may become a keyword. New-style classes now allow assignment to __name__ and __bases__. Interned strings are no longer immortal. sys.setcheckinterval() - the default value for this feature has changed from 10 to 100, for faster execution of interleaving multiple threads (by switching threads less frequently). Universal newlines - files opened for reading with the special mo...

  • Python Success Stories

    ...reversed this process. Not that it took me very long to learn the feature set. I wrote a working, usable fetchmailconf, with GUI, in six working days, of which perhaps the equivalent of two days were spent learning Python itself. This reflects another useful property of the language: it is compact -- you can hold its entire feature set (and at least a concept index of its libraries) in your head. C is a famously compact language. Perl is notoriously not; one of the things the notion "There'...

  • Parade of the PEPs

    ...reversed=<bool>" optional argument seems utterly application-specific. I would like to reject this because it doesn't solve a general enough problem in a general enough way, it just clutters the dictionary API. I'd rather add dict.popitem(key).
