Python 3.x renamed the low-level module 'thread' to '_thread' -- I don't see why in the documentation. Does anyone know?
回答1:
It looks like the thread module became obsolete in 3.x in favor of the threading module. See PEP 3108.
回答2:
It's been quite a long time since the low-level thread module was informally deprecated, with all users heartily encouraged to use the higher-level threading module instead; now with the ability to introduce backwards incompatibilities in Python 3, we've made that deprecation rather more than just "informal", that's all!-)
回答3:
I think the old thread module is deprecated in favour of the higher level threading module.
