Subject: python: Remove unused imports and variables.
X-Git-Url: http://git.cascardo.eti.br/?p=cascardo%2Fovs.git;a=commitdiff_plain;h=5697ca99019c1bf63a7df914554138b753fae886

python: Remove unused imports and variables.

This resolves the following flake8 error types:

  F841 local variable 'e' is assigned to but never used
  F401 'exceptions' imported but unused
