bpo-33431: Change description about doc in programming, faq.

[lyu-huiyang]

I think the description and in all cases in the standard library is not good. The method pop() that mutates an object will not return None .

Hi @lvhuiyang, thanks for contributing and welcome!

The CLA may take some time to be validated don't worry.

About your modification, as it's in an already long answer about a broader subject, I would go toward simplifying the paragraph (removing things) instead of complexifying it. Why not simply removing the (and in all cases in the standard library)?

For small documentation changes like this, next time it would be OK not to add a news entry
And for this one, imagine being someone reading the news and reading "Change description about programming, faq for https://docs.python.org/3/", what would you learn about the modification?
Maybe something like "Removed wrong statement in programming faq" would be clearer for the reader?

@JulienPalard Thank you for your reply, I agree with you about simplifying the paragraph. And I changed the news entry to be clearer.

I has submited a comment again. So this is a so small modification, if this PR is not necessary I will close.
