[chen-y0y0]

New submission from chen-y0y0 <cyy144881 at icloud.com>:

# I create a module:
# \sys.path\xxx.py
a = 9
# And:
>>> import xxx
>>> xxx.a
9
# I delete this imported module and modified this module:
del xxx
# \sys.path\xxx.py
a = 9
b = 8
# And re-import:
>>> import xxx
>>> xxx.b
# But:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: type object 'xxx' has no attribute 'b'
