code: def bitsetxor(b1, b2):

  	return res
docs: If b1 and b2 would be ``int`` s this would be ``b1 ^ b2`` :
  
  	>>> from py_register_machine2.engine_tools.operations import bitsetxor
  	>>> b1 = [1, 1, 1, 1]
  	>>> b2 = [1, 1, 0, 1]
  	>>> bitsetxor(b1, b2)
  	[0, 0, 1, 0]
  	>>> bin(0b1111 ^ 0b1101)
  	'0b10'
