I carefully redid your test, corrected, 3 times, and it works as expected.
Win 10, 3.9.0rc2.
>>> import a.tem3 as t
>>> t.b
Traceback (most recent call last):
File "<pyshell#23>", line 1, in <module>
t.b
AttributeError: module 'a.tem3' has no attribute 'b'
# Add 'b = 2' to a/tem3.py and save.
>>> import sys
>>> del sys.modules['a.tem3']
>>> import a.tem3 as t
>>> t.b
2
Without seeing exactly what you did and when, I can only guess that you
imported a version of xxx without the 'b' binding. I once added it but *forgot
to save* before re-importing. Note that dictionary deletion and importing are
well tested operations, so that bugs in normal imports are very unlikely. If
you really get a failure, there must be some relevant details that you have
omitted, like importing from a remote system that is locally cached, with the
local cache unchanged by editing the remote original. Or having an OS bug such
that saving a file does not update the 'last changed' time.
If you disagree with a closing, please request re-opening and give us a chance
to reproduce and discuss first rather than doing so yourself.
