My kludgey workaround goes something like this:


_xMax = []
for -whatever-:
  -big calculation leading to a value of x-
  _xMax.append( x )
  _xMax = [max(xMax)]
  xMax = _xMax[0]

Saves a line (and doesn't need to worry about None).  And of course, there is 
always the possibly evil:

_xMax = []
for -whatever-:
  -big calculation leading to a value of x-
  _xMax.append( x )
  xMax = max(_xMax)  #
