As well as those added intentionally.

Sometimes I wonder what it is that you see in Python and why you use it.
You're frequently complaining about features of the language. You go out of
your way to write in the style of Java/C/whatever in Python, which means
you get all the disadvantages of writing verbose and inflexible static
Java/C/whatever PLUS the inefficiency of dynamic Python, so the worst of
both worlds.

I genuinely don't see what you get out of using Python. Would you care to
explain? There must be something you like about it, even if it isn't the
ability to add attributes to (nearly) arbitrary objects without declaring
them, or the duck-typing of booleans.
