背景
在非开发环境经常需要做一下日期计算，就准备使用Python，顺便记下来学习的痕迹。
代码
1 1 # coding = utf-8 2 2 3 3 from datetime import * 4 4 5 5 ########################## 日期 ########################## 6 6 date_now = date.today() 7 7 print('now:', date_now) 8 8 print('year:', date_now.year) 9 9 print('month:', date_now.month) 10 10 print('day:', date_now.day) 11 11 12 12 date_tomorrow = date_now.replace(day = date_now.day + 1) 13 13 print('tomorrow:', date_tomorrow) 14 14 15 15 delta = date_tomorrow - date_now 16 16 print('tomorrow - now:', delta) 17 17 18 18 ########################## 时间 ########################## 19 19 time_now = time(13, 59, 59) 20 20 print('now time:', time_now) 21 21 print('hour:', time_now.hour) 22 22 print('minute:', time_now.minute) 23 23 print('second:', time_now.second) 24 24 print('next hour time:', time_now.replace(hour = time_now.hour + 1)) 25 25 26 26 ########################## 日期时间 ########################## 27 27 now = datetime.today() 28 28 print('date:', now.date()) 29 29 print('time:', now.time()) 30 30 31 31 ########################## 格式化 ########################## 32 32 print(datetime.today().strftime( '%Y-%m-%d %H:%M:%S %f' ) )
