如何清除Python threading.local对象？

如何清除Python实例的所有属性？

您可以清除它的底层属性

\uuuu dict\uuu

：

>>> l = threading.local()
>>> l
<thread._local object at 0x7fe8d5af5fb0>
>>> l.ok = "yes"
>>> l.__dict__
{'ok': 'yes'}
>>> l.__dict__.clear()
>>> l.__dict__
{}
>>> l.ok
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'thread._local' object has no attribute 'ok'

您还可以访问本地对象的字典：

  >>> mydata.__dict__
  {'number': 42}
  >>> mydata.__dict__.setdefault('widgets', [])
  []
  >>> mydata.widgets
  []

  >>> mydata.__dict__
  {'number': 42}
  >>> mydata.__dict__.setdefault('widgets', [])
  []
  >>> mydata.widgets
  []
