Not quite. An array is closer to a Python list - a tuple can be
thought of as a "frozen list", if you like. Lists can be added to,
removed from, and changed in many ways; tuples are what they are, and
there's no changing them (the objects inside it could be changed, but
WHAT objects are in it won't).

Python has no strict match to a C-style array with a fixed size and
changeable members; a Python list is closest to a C++ std::vector, if
that helps at all.
