If you don't know why private was introduced, what makes you think it is
a good feature to have?
Programmers in languages with "private, protected" etc usually end up
spending large amounts of time fighting with the compiler, because some
over-zealous other programmers made things private that shouldn't have
been.
Python finds a nice middle ground between languages which offer no
protection and those that encourage too much unnecessary protection. We
have a very strong convention not to rely on or use other people's
underscore variables, while still allowing people to inspect and even
modify those variables if necessary; but if you really, truly want to
hide the existence of class attributes you can write the class in C.
Explain to us, what *exactly* are you worried about? Suppose you write a
class, and have an underscore private attribute or method:
class MyClass:
def __init__(self):
self._spam = 1
Now what? What are you worried about happening if somebody else gets
access to your code, say they download it from Github or something, and
use that private attribute?
What harm are you trying to prevent?
