LGTM.
The 2.x docs were fixed in c9bf6e70308e, but this change was lost during
merging to 3.x in 3d866579117d.

Terry J. Reedy added the comment:
To modify what I said, Idle only auto-expands literal tabs entered into an
editor window with the Tab key. When one is doing such entry, all key
sequences are subject to interception, so this is nothing special.
Tabs chars put in a string with '\t' or '\x09'
Terry J. Reedy added the comment:
To me, this cries out for a public context manager ( believe there is a public
one in test.support, or something), so one can write
with stdout(ob):
print(stuff)
I am not sure, though, where the C.M.s should live.

I closed #24572 as a duplicate of this. It is the same issue except for
printing \r instead of \b. These issues are not about responses to keyboard
actions when entering text into an Idle editor window. During entry, just

https://docs.python.org/3/reference/expressions.html#id18
The string \u0327\u0043 does not normalize to the same string as \u00C7, as
combining characters are supposed to _follow_ the base character. (Some
consoles may happen to display them the same way,

Hmm, right. I see your point and also the analogy with yield. I could live
with (maybe) giving it a better error message suggesting to use parentheses for

It looks like perfectly valid syntax to me and I cannot see why it should be

not has a lower priority than unary -; this:
not a b
is parsed as:
not (a b)
How would you parse:
0 + not 0 + 0
?
Would it be parsed as:
0 + not (0 + 0)
?
Similar remarks could apply to yield:
0 + yield 0

“run ``import idlelib; idlelib.run`` within a try-except statement”: It might
be nice to say what exceptions are expected. My guess is ImportError if Idle or

The issue is the interaction between stacking and focus. I am pretty sure that
this is not a Python bug and that this issue should be closed. I suspect that
the behavior is not even a tk bug, but simply how Windows' graphics system work.

It may not be a pure Python bug, but it's definitely at least a tk bug (which
makes it a Python bug as long as tk is the canonical UI package in Python.)
Workarounds are nice, but a workaround fixes my specific problem here and now,
while leaving unknown numbers

If that would give a different sequence of random numbers,
I'm not sure that's acceptable in a bugfix release. Raymond
can shed a light.
You're right. It is not acceptable to give a different sequence of random

The implementation itself LGTM (nice use of decorator). New feature should be
documented. Needed changes in Doc/library/operator.rst and Doc/whatsnew/3.6.rst
