New submission from Bruce Frederiksen:
The 2.5 library documentation mentions the new GeneratorExit exception,
but does not show Generator Types with the new 'send', 'throw', 'close'
and '__del__' methods.

New submission from Bruce Frederiksen <[EMAIL PROTECTED]>:
There is no way to get generators to clean up (run their 'finally'
clause) when used as an inner iterable to chain:
>>> def gen(n):
... try:
... # do stuff yielding values
... finally:

Bruce Frederiksen <[EMAIL PROTECTED]> added the comment:
What you propose is not portable code. It won't work on jython or
ironpython or pypy because they don't have reference counting garbage
collectors that immediately reclaim objects.
Also I'm not asking that all c-b

Bruce Frederiksen <[EMAIL PROTECTED]> added the comment:
But the real Grammar doesn't include decorators on funcdef and classdef,
while the Language Reference document does. So the 'decorated' option
is not needed in the Language Reference (and, indeed, doesn't even
Bruce Frederiksen <[EMAIL PROTECTED]> added the comment:
The grammar definitions in the Language Reference are _not_ just a
straight copy of the Grammar. They have been reworked. (I don't know
why, perhaps to make it easier to understand)?
So the Grammar defines funcdef a

The definition for set_display in the Language Definition allows for
empty curly braces by enclosing expression_list | comprehension in
brackets ('[', ']'). These brackets should be removed, as empty curly

The definition of 'call' in the Language Reference refers to
'genexpr_for' which doesn't exist. Either 'genexpr_for' should be
changed to 'comp_for' or 'expression genexpr_for&#

I'm getting a "TypeError: bad argument type for built-in operation" on a
print() with no arguments. This seems to be a problem in both 3.1 and 3.1.2
(haven't tried 3.1.1).
I've narrowed the problem down in a very small demo pr
New submission from Bruce Frederiksen :
The python CLI always sets the __file__ variable, whether run as:
$ python foobar.py
or
$ python -m foobar
or
$ python
>>> import foobar # __file__ set in foobar module
The idle program sets the __file__ variable properly when you do t

I have also hit this error. I went to report it but found it already entered
(good news), but not resolved from nearly a year ago (bad news).
The error masked another bug that I had in my program and it took me quite
awhile to figure out what the real

OK, I see where I mis-diagnosed the problem. It seems that importing
smtplib (for example) shouldn't get confused with my email package. As
I understand it, using relative imports within a package should avoid
the problem of t

Being forced to number the arguments when using positional arguments in
a format string is difficult to maintain. Adding an argument to the
format string either requires renumbering all subsequent arguments, or

I was reading the 3.0 documentation:

No, IDLE compiles the module (with the 'compile' built-in using the 'exec'
