import datetime

end_time = 1525104000000
d = datetime.datetime.fromtimestamp(end_time / 1000, None)  # 时间戳转换成字符串日期时间
e = datetime.date.fromtimestamp(end_time /1000) # 时间戳转换成字符串日期
str1 = d.strftime("%Y-%m-%d %H:%M:%S.%f")
now = datetime.datetime.now()
aDay = datetime.timedelta(days=-1) # 减1天
now_aDay = now + aDay

print(d)  # 2018-05-01 00:00:00
print(e)  # 2020-03-15
print(str1) # 2018-05-01 00:00:00.000000
print(now) # 2020-03-16 22:54:26.09290
print(now.strftime(\'%Y-%m-%d\'))  # 2020-03-16
print(now_aDay.strftime(\'%Y-%m-%d\')) # 2020-03-15

相信很多人都容易搞混，好记性不如烂笔头
