python之time模块

time获取时间戳：

import time
print(time.time())

E:\python36\python3.exe E:/pj/test/test.py
1520243808.7411149

localtime获取当前时间对象,然后再去获取年月日时分秒的属性：

import time
a=time.localtime()
print (a)
print (a.tm_year)
print (a.tm_mon)
print (a.tm_mday)
print (a.tm_hour)
print (a.tm_min)
print (a.tm_sec)

E:\python36\python3.exe E:/pj/test/test.py
time.struct_time(tm_year=2018, tm_mon=3, tm_mday=5, tm_hour=18, tm_min=4, tm_sec=43, tm_wday=0, tm_yday=64, tm_isdst=0)
2018
3
5
18
4
43

asctime获取当前时间的标准格式：

import time
print(time.asctime(time.localtime()))

E:\python36\python3.exe E:/pj/test/test.py
Mon Mar  5 18:07:09 2018

strftime当前时间的格式化输出：

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

E:\python36\python3.exe E:/pj/test/test.py
2018-03-05 18:08:58
Mon Mar 05 18:08:58 2018

strptime和mktime时间格式化转时间戳：

import time
a=time.strftime('%a %b %d %H:%M:%S %Y',time.localtime())
print (a)
print (time.mktime(time.strptime(a,"%a %b %d %H:%M:%S %Y")))
