Both of those are assignment statements, so I'm not sure what you mean
by “get from … to”. To translate one assignment statement to a different
assignment statement, re-write the statement.


But I think you want to produce a new sequence from an existing sequence.

The ‘map’ built-in function is useful for that::

    sequence_of_numbers_as_text = ['1024', '1280']
    sequence_of_integers = map(int, sequence_of_numbers_as_text)

That sequence can then be iterated.

Another (more broadly useful) way is to use a generator expression::

    sequence_of_integers = (int(item) for item in sequence_of_numbers_as_text)


If you really want a tuple, just pass that sequence to the ‘tuple’
callable::

    tuple_of_integers = tuple(
            int(item) for item in sequence_of_numbers_as_text)

or::

    tuple_of_integers = tuple(map(int, sequence_of_numbers_as_text))
