时间处理

# timeStamp = 1381419600
# timeArray = time.localtime(timeStamp)
# otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray)
# print otherStyleTime   # 2013--10--10 23:40:00
# # 使用datetime
# timeStamp = 1381419600
# dateArray = datetime.datetime.utcfromtimestamp(timeStamp)
# otherStyleTime = dateArray.strftime("%Y--%m--%d %H:%M:%S")
# print otherStyleTime   # 2013--10--10 15:40:00

# 时间戳转换为格式化

import time

timeStamp = 1570695095

timeArray = time.localtime(timeStamp)

otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray)

print(otherStyleTime)

# 格式化转换成时间戳

import time

def str_to_timestamp(str_time=None, format='%Y-%m-%d %H:%M:%S'):

time_tuple = time.strptime(str_time, format) # 把格式化好的时间 转换成元祖

result = time.mktime(time_tuple) # 把时间元祖转换成时间戳

return int(result)

print(str_to_timestamp('2019-09-21 00:00:00'))

 

# 将时间转换成秒

def t2s(t):

h, m, s = t.strip().split(":")

return int(h) * 3600 + int(m) * 60 + int(s)

print(t2s('10:35:50'))

 

获取昨天日期

import datetime

t = datetime.date.today()

t2 = datetime.timedelta(-1)

print(t)

print(t2)

print(t+t2)

 

获取当前日期时间

import datetime

import time

print(time.strftime('%Y%m%d %H:%M:%S',time.localtime(time.time())))

 

获取当天凌晨

import datetime

import time

today = datetime.date.today()

print(today)

today_time = int(time.mktime(today.timetuple()))

print(time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(today_time)))

 

 

import datetime

# 获取当前时间

now = datetime.datetime.now()

# 获取今天零点

zeroToday = now - datetime.timedelta(hours=now.hour, minutes=now.minute, seconds=now.second,microseconds=now.microsecond)

# 获取23:59:59

lastToday = zeroToday + datetime.timedelta(hours=23, minutes=59, seconds=59)

print(lastToday)
