Question
How do you do 8? It corresponds to 7.
(7.)Write a function to_secs that converts hours, minutes and seconds to a total number of seconds.
Here are some tests that should pass:
def to_secs (h,m, s) :
haurs=h.360o
actual/Mr exPect
test(to_secs (2, 30, 10), 9010)
test(to_secs (2, 0, 0), 7200)
test(to_secs (0, 2, 0), 120)
test(to_secs (0, 0, 42), 42)
test(to_secs (0, -10, 10), -590)
mintes=m. 6
ReHrn hours+ minutes +s
8.) Extend to_secs so that it can cope with real values as inputs. It should always return an integer
number of seconds (truncated towards zero):
def to - secs ch, m,s)i
test(to_secs ( 2.5, 0, 10.71), 9010)
test(to_secs(2.433,0,0), 8758)
Write three functions that are the "inverses" of to_secs:
Opposite
