  • Unifying types and classes in Python 2.2

    ...expression super(C, self).m should only be used inside the implementation of method m in class C. Bear in mind that while self is an instance of C, self.__class__ may not be C: it may be a class derived from C (for example, D). The expression super(C, self).m, then, searches self.__class__.__mro__ (the MRO of the class that was used to create the instance in self) for the occurrence of C, and then starts looking for an implementation of method m following that point. For example, if ...

For example, when something goes wrong, they will be able to make a better mental model of the likely failure, which will allow them to fix or work around the problem. They will also be able to assess better when they can make the changes themselves and when they will need the services of an expert. They will be more able to converse with experts, since they will now s...

However, without programmability, there is no way I can make it try a couple of different numbers for a particular friend until one is answered, unless the cell phone vendor anticipated this particular feature. 3.

Moreover, the re.UNICODE flag is enabled automatically for unicode patterns, and can be disabled by specifying a new re.ASCII flag; as for bytes patterns, ASCII matching is the only option and trying to specify re.UNICODE for such patterns raises a ValueError.

  • Python Success Stories

    ...regularly pausing to look up new language and library features! This was my first clue that, in Python, I was actually dealing with an exceptionally good design. Most languages have so much friction and awkwardness built into their design that you learn most of their feature set long before your misstep rate drops anywhere near zero. Python was the first general-purpose language I'd ever used that reversed this process. Not that it took me very long to learn the feature set. I wrote a working, u...

For example, when running the expression r'(a)(b)?b' over 'ab', lastindex must be 1, not 2. Fixed bug #581080: sre scanner was not checking the buffer limit before increasing the current pointer. This was creating an infinite loop in the search function, once the pointer exceeded the buffer limit. The os.fdopen function now en...
