python 日期和时间

python 日期和时间 获得时间戳

import time  # 引入time模块
 
ticks = time.time()

获取当前时间分开形式(localtime):

import time

localtime = time.localtime(time.time())
print ( localtime)

输出:

time.struct_time(tm_year=2021, tm_mon=11, tm_mday=4, tm_hour=21, tm_min=48, tm_sec=3, tm_wday=3, tm_yday=308, tm_isdst=0)

取值可以通过 localtime .tm_year方式来单独取值

获得详细时间(datetime.now)

import datetime

print(datetime.datetime.now())

输出

2021-11-04 21:46:15.944999

字符串转时间类型(strptime)

import datetime

formats="%s-%02d-%02d" % (year, mon,day)
this_mon=datetime.datetime.strptime(formats,"%Y-%m-%d")

时间类型转字符串(strptime)

	import datetime
	
	localtimes=time.localtime()
    year=localtimes.tm_year
    mon=localtimes.tm_mon
    day=localtimes.tm_mday
    day_str="%s-%02d-%02d" % (year, mon,day)
	this_day=datetime.datetime.strptime(day_str,"%Y-%m-%d")

时间类型减或加去多少天(timedelta)

今天减去一天:

import datetime

时间类型-datetime.timedelta(days=i)
