First solution in Clear category for Time Converter (24h to 12h) by vlad.bezden
"""
You prefer a good old 12-hour time format.
But the modern world we live in would rather use the 24-hour format and you see
it everywhere. Your task is to convert the time from the 24-h format into
12-h format by following the next rules:
- the output format should be 'hh:mm a.m.'
(for hours before midday) or 'hh:mm p.m.' (for hours after midday)
- if hours is less than 10 - don't write a '0' before it. For example: '9:05 a.m.'
Input: Time in a 24-hour format (as a string).
Output: Time in a 12-hour format (as a string).
Precondition:
'00:00' <= time <= '23:59'
"""
def time_converter(time: str) -> str:
hours, minutes = map(int, time.split(":"))
am_pm = "a.m." if hours < 12 else "p.m."
hours = hours % 12
return f"{hours if hours else 12}:{minutes:02d} {am_pm}"
if __name__ == "__main__":
assert time_converter("12:30") == "12:30 p.m."
assert time_converter("09:00") == "9:00 a.m."
assert time_converter("23:15") == "11:15 p.m."
assert time_converter("00:00") == "12:00 a.m."
print("DONE!")
