Walrusing Around

This is -- well -- it is what it is. I don't have to like it.

>>> t_s = (8063599, 0)
>>> fields = [(t_s := divmod(t_s[0], b))[1] for b in (60, 60, 24, 7)]
>>> list(reversed(fields + [t_s[0]]))
[13, 2, 7, 53, 19]


It works and shows how the assignment operator works.

The point here is to convert a timestamp into ISO week, day, hour, minute, second. 13th week, 2nd day, 7h, 53m, 19s.

The divmod() function returns a two-tuple, which the assignment operator can't decompose. Instead, we decompose it by wrapping the whole thing in ()[1].

Works.
