Please include how to use the thread_name_prefix method argument (new to Python 3.6) in the example: 17.4.2.1. ThreadPoolExecutor Example

[jftuga]

I have updated the Python 3.6 example for 17.4.2.1. ThreadPoolExecutor Example. Please see the attachment. On my system this is the output:

thread name: loader_0

Could you please consider adding this to the official documentation?

[jftuga]

Can this be added to Python 3.7?

Thanks.

Hi John,

Would you be able to make a GitHub pull request for your change? Since CPython development has moved to GitHub, you may have a better chance of a review with a PR.

[csabella]

This seems like a reasonable request. A description of thread_name_prefix should probably also be added to the body of the class description instead of just in the versionadded directive.

Assigning to @Mariatta for the sprints.

Nosying @gregory.p.smith as he added the parameter in bpo-27664.
