时间戳的一些转化

import time,datetime
#时间戳
timestamp=int(time.time())
# #转换成localtime
time_local=time.localtime(timestamp)
# #转换成时间格式：%Y_%m_%d %H:%M:%S
dt=time.strftime("%Y-%m-%d",time_local)
print(dt)
if dt == '2022-01-05':
    print(True)
else:
    print(False)

# datetime
times = datetime.datetime.now()
res = times.strftime("%Y-%m-%d")
print(type(res))
if dt == res:
    print(True)
else:
    print(False)

将时间戳转换为年月日时分秒格式：
import datetime
timeStamp = 1511169651
dateArray = datetime.datetime.utcfromtimestamp(timeStamp)

print dateArray
otherStyleTime = dateArray.strftime("%Y-%m-%d %H:%M:%S")

print otherStyleTime

将年月日时分秒格式转换为时间戳
import time

a = "2017-11-14 13:30:00"


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

timeStamp = int(time.mktime(timeArray))

print timeStamp

 

两时间相减算出差多少天

import datetime
d1 = datetime.datetime(2007, 2, 16)
d2 = datetime.datetime(2004, 12, 31)
ss = (d1 - d2).days
print(ss)

 

# 可用算出前几天
for i in range(6,-1,-1):
        day = datetime.datetime.now() - datetime.timedelta(days=i)
        start = datetime.datetime.strftime(day,'%Y-%m-%d')
        print(start)
day = datetime.datetime.now()
end = datetime.timedelta(days=1)
aaa = (day - end).strftime('%Y-%m-%d')
# print(end)
print(day)
print(aaa)
