PEP 8: Add an exmple for blank lines between groups of imports

[tiagoboldt]

PEP 8 mentions that a white line should be included between import types, but does not provide an example for it. People quickly browsing the documentation might overlook this detail. Adding an example ensures readers visualize this recommendation.

• Change is either:
  • To a Draft PEP
  • To an Accepted or Final PEP, with Steering Council approval
  • To fix an editorial issue (markup, typo, link, header, etc)
• PR title prefixed with PEP number (e.g. PEP 123: Summary of changes)

-0; I don't think this is needed. There's not much else this line could be interpreted as.

Consider this non-blocking if another editor wants to merge, though.

-0.5, also non-blocking but I don't really see the need to have examples of everything. If someone wants to make a separate page somewhere with good and bad examples for everything, sure, but it doesn't need to be part of the main document (and doesn't even need to be anything official - it could just be a page on the Python wiki or something).

@tiagoboldt Thanks for the contribution, but I agree with the other comments. Not everything needs an example, and adding more text to the PEP can detract from its overall readability. Cheers!
