  The correct way to do this is:=20

  def mything(a, b, c=3DNone):=20
   """ do something, like check if 'c' is not None """=20
   if c:=20
    print a, b, c=20
   else:=20
    print a, b=20

You may want to be careful testing for c being true rather than testing =
None specifically since:

    mything("spam", "eggs", []) # or () or "" or 0 or some instances.

will take the second branch which may not be want you want. It's =
probably better to use:

def mything(a, b, c=3DNone):=20
 """ do something, like check if 'c' is not None """=20
 if c is not None:=20
  print a, b, c=20
 else:=20
  print a, b=20
