Does Python have “private” variables in classes?

Question

I\'m coming from the Java world and reading Bruce Eckels\' Python 3 Patterns, Recipes and Idioms.

While reading about classes, it goes on to say that in Py

Sorry guys for "resurrecting" the thread, but, I hope this will help someone:

In Python3 if you just want to "encapsulate" the class attributes, like in Java, you can just do the same thing like this:

class Simple:
    def __init__(self, str):
        print("inside the simple constructor")
        self.__s = str

    def show(self):
        print(self.__s)

    def showMsg(self, msg):
        print(msg + ':', self.show())

To instantiate this do:

ss = Simple("lol")
ss.show()

Note that: print(ss.__s) will throw an error.

In practice, Python3 will obfuscate the global attribute name. Turning this like a "private" attribute, like in Java. The attribute's name is still global, but in an inaccessible way, like a private attribute in other languages.

But don't be afraid of it. It doesn't matter. It does the job too. ;)
