Clock
With two arms, a 12-hour clock runs from 00:00 to 11:59. One minute after 11:59, it goes back to 00:00.
You will write a class Clock that implements the behaviors of such a clock via the following methods:
● def _init__(self, initial_time: str) sets up the clock to the specified initial_time, which is
guaranteed to be given in the format hh:mm (e.g., 11:24, 1:05, 08:07). Importantly, we guarantee
that the given initial_time will be between 00:00 and 11:59.
●
●
def forward(self, minutes: int) advances the time of the clock by minutes minutes. Keep in
mind that our clock cannot display any number outside its range. Therefore, adjust the result
accordingly. For example, adding 30 minutes to 11:40 will result in 00:10. The minutes parameter
can be so large that the clock wraps around several times (e.g., 3800 minutes).
def rewind (self, minutes: int) turns the time of the clock back by minutes minutes. Be careful
about the clock wrapping around. For example, subtracting 30 minutes from 12:15 will result in
11:45. The minutes parameter can be so large that the clock wraps around several times (e.g., 3800
minutes).
TEST CASES
def get_hour (self) -> int returns the hour of the clock. For example, if the current clock is 09:44,
this method returns the number 9.
def get_minute(self) -> int returns the minute of the clock. For example, if the current clock is
09:44, this method returns the number 44.
def reset (self) resets the clock to 0 hour and 0 minute.
An example usage of the clock class is below. Note that, in general, aside from
may be called in any order.
clock Clock ('01:01')
assert (clock.get_hour()==1)
assert (clock.get_minute()==1)
clock.rewind (2) # should be 0:59
assert (clock.get_hour()==0)
assert (clock.get_minute()==59)
clock. forward (63) # should be 2:02
assert (clock.get_hour () == 2)
assert (clock.get_minute()==2)
clock.reset() # should be 0:00
assert (clock.get_hour()==0)
assert (clock.get_minute()==0)
clock. forward (2423) # should be 4:23
