如果给定 datetime.datetime 对象,则保留时间信息 不使用 try/catch,而是使用calendar.monthrange来自 stdlib 中的calendar模块: import datetime import calendar def add_one_month(orig_date): # advance year and month by one month new_year = orig_date.year new_month = orig_date.month + 1 # note: i...

datetime.datetime(2000, 2, 3, 5, 35, 2) 不出意外,我们成功创建了 datetime 对象。我们还可以更明确地将关键字参数传递给 datetime 构造函数: datetime(year=2000, month=2, day=3, hour=5, minute=35, second=2) Output: datetime.datetime(2000, 2, 3, 5, 35, 2) ...

Python的datetime可以处理2种类型的时间,分别为offset-naive和offset-aware。前者是指没有包含时区信息的时间,后者是指包含时区信息的时间,只有同类型的时间才能进行减法运算和比较。datetime模块的函数在默认情况下都只生成offset-naive类型的datetime对象,例如now()、utcnow()、fromtimestamp()、utcfromtimestamp()和...
