沒有用于timedelta對象的內(nèi)置格式化程序，但您自己很容易做到：days, seconds = duration.days, duration.seconds

hours = days * 24 + seconds // 3600

minutes = (seconds % 3600) // 60

seconds = seconds % 60

或者，等價地說，如果您使用的是Python 2.7+或3.2+：seconds = duration.total_seconds()

hours = seconds // 3600

minutes = (seconds % 3600) // 60

seconds = seconds % 60

現(xiàn)在您可以按需打印：'{} minutes, {} hours'.format(minutes, hours)

例如：def convert_timedelta(duration):

days, seconds = duration.days, duration.seconds

hours = days * 24 + seconds // 3600

minutes = (seconds % 3600) // 60

seconds = (seconds % 60)

return hours, minutes, seconds

td = datetime.timedelta(2, 7743, 12345)

hours, minutes, seconds = convert_timedelta(td)

print '{} minutes, {} hours'.format(minutes, hours)

這將打印：9 minutes, 50 hours

如果你想得到“10分鐘，1小時”而不是“10分鐘，1小時”，你也需要手動完成：print '{} minute{}, {} hour{}'.format(minutes, 's' if minutes != 1 else '',

hours, 's' if minutes != 1 else '')

或者您可能希望編寫一個english_plural函數(shù)來為您執(zhí)行's'位，而不是重復(fù)您自己。

從你的評論來看，聽起來你真的想把日子分開。更簡單的是：def convert_timedelta(duration):

days, seconds = duration.days, duration.seconds

hours = seconds // 3600

minutes = (seconds % 3600) // 60

seconds = (seconds % 60)

return days, hours, minutes, seconds

如果要將其轉(zhuǎn)換為要存儲在數(shù)據(jù)庫中的單個值，然后將該單個值轉(zhuǎn)換回格式，請執(zhí)行以下操作：def dhms_to_seconds(days, hours, minutes, seconds):

return (((days * 24) + hours) * 60 + minutes) * 60 + seconds

def seconds_to_dhms(seconds):

days = seconds // (3600 * 24)

hours = (seconds // 3600) % 24

minutes = (seconds // 60) % 60

seconds = seconds % 60

return days, hours, minutes, seconds

所以，把它放在一起：def store_timedelta_in_database(thingy, duration):

seconds = dhms_to_seconds(*convert_timedelta(duration))

db.execute('INSERT INTO foo (thingy, duration) VALUES (?, ?)',

thingy, seconds)

db.commit()

def print_timedelta_from_database(thingy):

cur = db.execute('SELECT duration FROM foo WHERE thingy = ?', thingy)

seconds = int(cur.fetchone()[0])

days, hours, minutes, seconds = seconds_to_dhms(seconds)

print '{} took {} minutes, {} hours, {} days'.format(thingy, minutes, hours, days)
