There should be no clash between the names if your object has
an "open" method.

When an object has an "open" method, it is either referred to
by

self.open()

or 

objname.open()

So you should be able to call (the builtin) open from within 
your object, and there should be no name clash, because you have not
explicitly specified the open method on your object (i.e. "self").

Here is an example:

class  Sketch:

  def  __init__(self, filename):
    # Note this calls __builtin__.open
    self.outchan = open(filename, "wt") 

  def  open(self):
    self.outchan.write("Opening window\n")

  def  doit(self, o):
    self.outchan.write("Goodbye, %s!\n" % o)

  def  close(self):
    self.outchan.write("Closing window\n")
    self.outchan.close()

  def  defenestrate(self, o):
    #  Note this calls self.open
    self.open()              
    self.doit(o)
    self.close()

>>> s = Sketch('sketch.log')
>>> s.defenestrate('tabby')
