一、时间字符串格式转化:
1、时间格式的字符串转时间
from time import strptime
>>> s_time = strptime("2020-01-10 09:29:15", "%Y-%m-%d %H:%M:%S")
>>> print(s_time)
time.struct_time(tm_year=2020, tm_mon=1, tm_mday=10, tm_hour=9, tm_min=29, tm_sec=15, tm_wday=4, tm_yday=10, tm_isdst=-1)
>>> print(s_time.tm_year)
2020
>>> s_time = strptime("2020-01", "%Y-%m")
>>> print(s_time)
time.struct_time(tm_year=2020, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=2, tm_yday=1, tm_isdst=-1)
>>> print(s_time.tm_year)
2020
2、时间转字符串
>>> from time import strptime, strftime, localtime
>>> print(localtime())
time.struct_time(tm_year=2020, tm_mon=1, tm_mday=10, tm_hour=9, tm_min=35, tm_sec=42, tm_wday=4, tm_yday=10, tm_isdst=0)
>>> print(localtime().tm_year, localtime().tm_mday)
2020 10
>>> print(type(strftime("%Y-%m-%d %H:%M:%S", localtime())))
<class ‘str‘>
>>> print(strftime("%m-%d-%Y %H:%M:%S", localtime()))
01-10-2020 09:42:49
>>> print(type(strftime("%m-%d-%Y %H:%M:%S", localtime())))
<class ‘str‘>
二、闰年判断
import calendar
from datetime import date
from time import strptime, strftime, localtime
calendar中的 isleap可以返回True(闰年)和False(不是闰年)
>>> print(calendar.isleap(2012))
True
>>> print(calendar.isleap(date.today().year))
True
>>> print(calendar.isleap(localtime().tm_year))
True
ss = "2013"
>>> print(calendar.isleap(datetime.datetime.strptime(ss, "%Y").year))
False
