function call problem in class?

[Davy]

Hi all,

I have write a simple class, I want the function two() to call private
function __one(), but there is an error :
NameError: global name '_simple__one' is not defined, how to work
around it

class simple:
def __one(self):
print "Hello"
def two(self):
__one()
print "world"

if __name__ == '__main__':
s = simple()
s.two()

Any suggestion is welcome!
Best regards,
Davy

class simple:
def __one(self):
print "Hello"
def two(self):
__one()
print "world"

if __name__ == '__main__':
s = simple()
s.two()

Note that your problem is not related to mangled names: replacing __one by
one raises a similar exception.
Remember that "self" is not implicit: you must use self.__one()

"private" methods (and atributes in general) use a single underscore:
_one. Double underscores __one are reserved for the (rare) cases when you
want to ensure unique names (or name clashes are expected).
