Okay, but (A) I did not think Python had constructor methods and (B) why do I always see methodName(self): like in your example?

Two underscores signify either a constructor method or a built in method I
think.  Like the str method.  If you want to define string formatting with
your class its defined by two underscores before and after the method name. 
example __str__(self):

In python, why are some method names surrounded by two underscores? Even
some filenames have these two underscores, though I imagine that is more of a convention than anything else. What do the underscores mean, if anything?
