Private methods, functions and variables are very common in programming
languages. But Python doesn't support private. It has conventions for naming so
considered private but not private. Most of the time private is never required,
what Python provides is more than enough. But the need for private come into
place when we're dealing with passphrases and servers. For example consider
this code,
class A:
def get():
// code to get the password
self.password = password
Now consider this,
>>> x = A(); x.get(); x.password
See what just happened? Someone just got the member variable value that the
person wasn't supposed to.
I suggest to add private support for functions (module __all__ methods to be
more clear), methods and variables (module __all__ variables or class
variables).
(I very bad at reading PEPs so I may miss out something critical that's been
explained already (sometimes I miss out a feature in a PEP and think about
suggesting that feature when it's already there and then I realize "Oh! It's
already here in this PEP"). If that's the case then please correct me.)
