all: Update Python code to conform to latest black formatting.

Updating to Black v20.8b1 there are two changes that affect the code in
this repository:

- If there is a trailing comma in a list (eg [], () or function call) then
  that list is now written out with one line per element.  So remove such
  trailing commas where the list should stay on one line.

- Spaces at the start of """ doc strings are removed.
