    ...constants with a leading minus sign would come out with the wrong sign. ("Unsigned" hex/oct constants are those with a face value in the range sys.maxint+1 through sys.maxint*2+1, inclusive; these have always been interpreted as negative numbers through sign folding.) E.g. 0xffffffff is -1, and -(0xffffffff) is 1, but -0xffffffff would come out as -4294967295. This was the case in Python 2.2 through 2.2.2 and 2.3a1, and in Python 2.4 it will once again have that value, but according t...

  • Python 2.4.1 - Release Notes

    ...constants into a single constant. SF bug #513866: Float/long comparison anomaly. Prior to 2.4b1, when an integer was compared to a float, the integer was coerced to a float. That could yield spurious overflow errors (if the integer was very large), and to anomalies such as long(1e200)+1 == 1e200 == long(1e200)-1. Coercion to float is no longer performed, and cases like long(1e200)-1 < 1e200, long(1e200)+1 > 1e200 and (1 << 20000) > 1e200 are computed correctly now. Extension...

Deibel noted that some people strongly want python.org to showcase "best of breed" projects, and others want python.org to avoid favoring specific projects.

  • What's new in Python 2.3

    ...declarations - you can put a comment of the form "# -- coding: <encodingname> --" in the first or second line of a Python source file to indicate the encoding (e.g. utf-8). (PEP 263 phase 1) Codec error handling callbacks - this allows for flexible handling of encoding errors. (PEP 293) File objects are now their own iterators. This makes multiple interrupted iterations over the same file more reliable. The xreadlines() method and module are now deprecated. The in operator ca...

    ...declarations. It is illegal to assign to the name __debug__, which is set when the interpreter starts. It is effectively a compile-time constant. A warning will be issued if a global statement for a variable follows a use or assignment of that variable. Standard library unittest.py, a unit testing framework by Steve Purcell (PyUNIT, inspired by JUnit), is now part of the standard library. You now have a choice of two testing frameworks: unittest requires you to write testcases as separate co...
