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.
That's only a problem if you have untrusted code running in the same Python interpreter as privileged code. There's fundamentally no way that you can get the password without the untrusted code also being able to get it. Do you have an actual use-case where you have passphrases like this? How does the "code to get the password" do it, and how do you ensure that the unprivileged code can't just do the same thing? ChrisA
