- A new command line option, -Q<arg>, is added to control run-time
|
||||
warnings for the use of classic division. (See PEP 238.) Possible
|
||||
values are -Qold, -Qwarn, and -Qnew. The default is -Qold, meaning
|
||||
the / operator has its classic meaning and no warnings are issued.
|
||||
Using -Qwarn issues a run-time warning about all uses of classic
|
||||
division for int, long, float and complex arguments. Using -Qnew is
|
||||
questionable; it turns on new division by default, but only in the
|
||||
__main__ module. You can usefully combine -Qwarn and -Qnew: this
|
||||
gives the __main__ module new division, and warns about classic
|
||||
division everywhere else.

- Tools/scripts/fixdiv.py has been added which can be used to fix

division operators as per PEP 238.

Build

- If you are an adventurous person using Mac OS X you may want to look at

Mac/OSX. There is a Makefile there that will build Python as a real Mac

application, which can be used for experimenting with Carbon or Cocoa.
