Help for simplifying code

[perfringo]

With code above you will get NameError (if you haven't somewhere in your code defined none, which would be bad practice).

a, b, c are the same in both cases, so no need to write those two times or put into conditionals. If you like 'clever' one-liners then you can do following regarding x, y, z:

>>> condition = ''
>>> x, y, z = ([x, None][bool(condition)] for x in range(10, 13))
>>> x, y, z
(10, 11, 12)
>>> condition = 'abc'
>>> x, y, z = ([x, None][bool(condition)] for x in range(10, 13))
>>> x, y, z
(None, None, None)
