python時間的獲取方法

一、獲取當前時間

import datetime

# 2019-7-9
print
(datetime.datetime.now(
).year)
# 2019
print
(datetime.datetime.now(
).month)
# 7print
(datetime.datetime.now(
).day)
# 9#上面的結果是正數型
#下面獲取字串型
print
(datetime.datetime.now(
).strftime(
'%m'))
# '07'
print
(datetime.datetime.now(
).strftime(
'%d'))
# '09'
print
(datetime.datetime.now(
).strftime(
'%y'))
# '19'
print
(datetime.datetime.now(
).strftime(
'%y'))
# '2019'
