[issue6453] Improve bool TypeError message

New submission from Terry J. Reedy <tjreedy [at] udel>:

>>> cc=c()
>>> bool(cc)
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
bool(cc)
TypeError: __bool__ should return bool or int, returned int

This is slightly jarring.
Adding ' 0 or 1' after 'or int' would be nice (and trivial).
Adding str(val) at the end after type(val) would be even nicer.

R. David Murray <rdmurray [at] bitdance> added the comment:

The error message is in error. Int is not allowed in 3.x, only bool.
This is thus superseded by issue 6428, which has already been fixed.

Phooey. I searched for 'bool TypeError' but it failed to return 6428.
I will ask on py-dev why not.

Testing.
I am 99.9% sure *I* did not reopen. Testing to see if OP post auto-reopens.

Must have been random glitch. I certainly did not change state and priority.

R. David Murray <rdmurray [at] bitdance> added the comment:

On your test post I got deleted from the nosy list. Was that intentional?

I wonder if your browser is doing something weird with the form field
settings. Or it may have as you say been a random thing...I know that
has happened to me once or twice where I refreshed the page in an odd
order and reset some fields I wasn't intending to reset.

yes, I was trying to avoid bothering you with the noise.
This is one of those 'everything gone wrong' situations.
If only I had unselected 'open only' when I did the search...
