How do I convert between tuples and lists?
The tuple function converts any sequence (actually, any iterable) into a tuple with the same items in the same order.
For example, tuple([1, 2, 3]) yields (1, 2, 3) and tuple(‘abc’) yields (‘a’, ‘b’, ‘c’). If the argument is a tuple, it does not make a copy but returns the same object, so it is cheap to call tuple when you aren’t sure that an object is already a tuple.
The list function converts any sequence or iterable into a list with the same items in the same order. For example, list((1, 2, 3)) yields [1, 2, 3] and list(‘abc’) yields [‘a’, ‘b’, ‘c’]. If the argument is a list, list makes a copy just like seq[:] would.
