You are expecting 4 items back from the sleep_seconds_control function
but you only return 1 (seconds). The left-hand side should either just
be `secs = ...` or you should change your function to return all 4 items.
What the error means is that the interpreter is trying to iterate over
the results from your function in order to divide it into the 4
variables on the left-hand side.
