[Python-Dev] Example for "property" violates "Python is not a one pass compiler"

Mon Sep 5 18:04:33 CEST 2005

Here is an example from the "Python Library Reference", Section 2.1 
"Built-in Functions":
class C(object):
 def getx(self): return self.__x
 def setx(self, value): self.__x = value
 def delx(self): del self.__x
 x = property(getx, setx, delx, "I'm the 'x' property.")
It works. But if I put the property statement first:
class C(object):
 x = property(getx, setx, delx, "I'm the 'x' property.")
 def getx(self): return self.__x
 def setx(self, value): self.__x = value
 def delx(self): del self.__x
I get the error:
 NameError: name 'getx' is not defined
Does this violate the principle "Python is not a one pass compiler"? 
Normally I can use any method of a class anywhere in the definition of 
the class.
