is there a whitespace-free python convention?

Yes. See the script pindent.py in Tools/scripts in your Python
distribution. It basically closes every intented block with an "end"
comment. The script can be used both to add this sort of marking, and
to remove it -- and restore indentation if it has been destroyed.

This, according to the pindent convention,

  def foobar(a, b):
  if a == b:
  a = a+1
  elif a < b:
  b = b-1
  if b > a: a = a-1
  # end if
  else:
  print 'oops!'
  # end if
  # end def foobar

is equivalent to

  def foobar(a, b):
     if a == b:
         a = a+1
     elif a < b:
         b = b-1
         if b > a: a = a-1
         # end if
     else:
         print 'oops!'
     # end if
  # end def foobar

or even

  def foobar(a, b):
     if a == b:
         a = a+1
     elif a < b:
         b = b-1
         if b > a: a = a-1
     else:
         print 'oops!'

Since this script has been in the Python distro for years, it seems
like the most "standard" convention to adopt, IMO.
