Python日期格式转换

字符串日期转为datetime类型

import datetime

time = '1994-01-19 00:00:00'
time = datetime.datetime.strptime(time,'%Y-%m-%d %H:%M:%S')
print(time,type(time))
输出结果：
1994-01-19 00:00:00  <class 'datetime.datetime'>

datetime类型转为字符串类型

import datetime
time = datetime.datetime.strftime(datetime.datetime.now(),'%Y-%m-%d %H:%M:%S')
print(time,type(time))
输出结果：
2020-09-17 13:17:57 <class 'str'>

时间戳转为datetime类型

10位时间戳
time = datetime.datetime.utcfromtimestamp(float(1580818427))
13位时间戳
time = datetime.datetime.utcfromtimestamp(float(1580818427123)/1000)

datetime类型转为时间戳

time_ = datetime.datetime.timestamp(datetime.datetime.now())

字符串类型转为时间戳

time_ = ‘1994-01-19 00:00:00’
time_ = time.strptime(time_,’%Y-%m-%d %H:%M:%S’)
time = timestamp = time.mktime(time_)

获取当前时间（含日期）

time = datetime.datetime.now()

获取当前时间（不含日期）

time = datetime.datetime.time(datetime.datetime.now())

获取近几天的日期

day = datetime.datetime.today() – datetime.timedelta(days=7)
for i in range(7):
print(day – datetime.timedelta(days=(-i)))
