Question:

How does one use variable length arguments for function calls in Python?

James G.
Answer:

Using either *args or **kwargs. *args is for lists, tuples, and comma separated values in a function call. **kwargs is for keyword arguments, such as maps or values in a function call that are assigned to a certain key.

Question:

Why can we not create a generic array without the use of typecasting and Array native methods?

James G.
Answer:

Because Java's type erasure hides run-time type argument to generic classes, such that one can reference arrays only through the erasure of the generic type, i.e: for generic $$<T extends Foo>$$ one should use an array defined as $$Foo[]arr;$$
