You are completely right.

I would rather have a specific bug than a general guideline (even if it
is correct) but I will keep this bug report as wishlist to serve as a
reminder.

Title:
  "if not <variable>" instead of "if <variable> is None"

Status in OpenERP Server:
  Confirmed

Bug description:
  In a lot of places (I greped "if +not +\w+:" and found tons of these)
  the function definition says <variable>=None and then check if the
  variable is false then creates an empty var. In python empty vars are
  usually false, so if someones passes an empty var the function will
  create a new one, both creating more objects than it needs to and
  making it way harder to test openerp code. Changing it to if
  <variable> is None is both more semantically correct and will make the
  problem go away.
