This used to return an "infinity" value on most platforms. <p><li> The 3-argument builtin pow() no longer allows a third non-None argument if either of the first two arguments is a float, or if both are of integer...

  ...inter to the default encoded string data instead of to the raw UTF-16. Py_BuildValue accepts B format (for bgen-generated code). Internals On Unix, fix code for finding Python installation directory so that it works when argv[0] is a relative path. Added a true tnicode_internal_encode() function and fixed the unicode_internal_decode function() to support Unicode objects directly rather than by generating a copy of the object. Several of the internal Unicode ...

• Notes

  ...InternalCall(). It is still the case that the returned code object might be entirely insane. Subclasses of string can no longer be interned. The semantics of interning were not clear here -- a subclass could be mutable, for example -- and had bugs. Explicitly interning a subclass of string via intern() will raise a TypeError. Internal operations that attempt to intern a string subclass will have no effect. Bug 1003935: xrange() could report bogus OverflowErrors. Documented what xrange() in...

• Parade of the PEPs

  ...int $"The area of a $x by $y rectangle is $z" is very questionable, but none of the alternatives I've seen proposed (e.g. i"...") look very good either. We can't just always turn on string interpolation in literals because that would break existing code. Maybe "from __future__ import interpolation" would enable interpolation in string literals? (Only in literals!) There's also the question whether to allow arbitrary expressions like print "The area is ${x*y}" PEP 2...

  ...integers, ok? Her: Okay. Me : So, you can add them, subtract them, and multiply them in a program, right? Her: Um. Sure. Me : Now let's say that you divide them-- Her: But that makes no sense! Integers form a ring, not a field. You did say you were taking these numbers from Z, right? Me : Uh, yeah. So there you have it. The non-programmer viewpoint. (With which I conveniently agree.) "Integer division" is hokey and shouldn't be spelled "/", even if C wants to....
