[Tutor] Does Python and its standard libraries use semantic versioning?

[boB Stepp]

I have been reading the interesting web page "Semantic Versioning
2.0.0" at https://semver.org/  I like how its use can supposedly make
"dependency hell" a thing of the past.  So I am wondering if Python
and its standard libraries make use of semantic versioning as
described in this article?  But I suppose that for third party
libraries anything goes?

TIA!
