Python之时间日期操作

常用时间操作的函数汇总， 涵盖 常用的time   datetime

1.计算两个日期相差天数

import datetime

str1 = '2021-10-20'
str2 = '2021-10-22'
date1 = datetime.datetime.strptime(str1[0:10], '%Y-%m-%d')
date2 = datetime.datetime.strptime(str2[0:10], '%Y-%m-%d')

days = (date2-date1).days

2.获取日期的开始与结束时间

import datetime

today = datetime.date.today()
min_today_time = datetime.combine(today, time.min)
max_today_time = datetime.combine(today, time.max)

# 昨天的日期
yesterday = today - datetime.timedelta(days=1)
