Py_UNICODE has been deprecated since PEP 393 (Flexible string representation).
wchar_t* cache in the string object is used only in deprecated APIs.
It waste 1 word (8 bytes on 64bit machine) per string instance.
The deprecated APIs are documented as "

So Python 3.8 doesn't show warning for them.
Ah, no problem. Thanks for checking up on that.

Hmm, okay. At the least though, it does mean we have to be a bit more
vigilant
Worth noting is that there is an existing loop-breaking mechanism,
but only for the newest exception being raised. In particular, option (4)
is actually the current behavior if the the most recent exception
participates in a cycle:
Python 3.9.0b1
>>> A, B, C, D, E = map(Exception, "ABCDE"

I think we should separate the questions of what to do when (1) setting the

Hello,
thank you for making Python and the neat inspect module.
I would love to hear your opinion on the following aspect of inspect
that I believe might be worth improving:
Consider the following program saved in a file (say hello.py):
import inspect
def hello():
print("Hello World")
p
IMO it is up to the offending module to provide an API for advertising
which variant of those functions is accepted. This seems out of scope for
inspect.

Hi INADA-san,
IMO Python 3.11 is too early because we don't emit a
DeprecationWarning on every single deprecation function.
1) Emit a DeprecationWarning at runtime (ex: Python 3.10)
2) Wait two Python releases: see
https://discuss.python.org/t/pep-387-backwards-compatibilty-policy/4421
3) Remove
Isn't it more Pythonic to simply call the function and an alternative path
to handle the exception, anyway? Half of os needs to be tested for
NotImplementedError or OSError if it's going to run anywhere outside the
development environment anyway, otherwise you're stuck with only the most
basic func
If I run the following program (using Python 3.8.3 on a Windows 10 laptop):
import sys, time
for i in range(1,11):
sys.stdout.write('\r%d' % i)
time.sleep(1)
As intended, it displays '1', replacing it at 1-second intervals with
'2', '3' ... '10'.
Now run the same code inside the REPL:

In Python 2, the 'write()` method returns None, which is suppres
Oh, good point! I forgot about that and was, uh, looking in the wrong

The whole point of the REPL is to evaluate an
expression and have the result printed. (That's the P in REPL :-)
Still, it's a bit surprising that it prints results of
expressions within a compound statement, not just at the
top level.
