Quick question about private/public methods

[modman]

Why does python not provide for this? it can not possibly hurt any 
functionality can it? I sort of like the public/private Idea cause it 
hides the actual methods from the person using the class and the person 
only needs to know a few little things about what they can pass to the 
method it also makes the implementation of a class easier to understand 
when public methods like getEggType() and spamType() are used.

just wondering cause I was messing with Python just before I started 
into C++ at school and I thought that the public/private Idea was pretty 
cool.

Thanks,
