英文版：
Write a program to count the number of days between two dates.
The two dates are given as strings, their format is YYYY-MM-DD as shown in the examples.
Example 1:
Input: date1 = "2019-06-29", date2 = "2019-06-30" Output: 1
Example 2:
Input: date1 = "2020-01-15", date2 = "2019-12-31" Output: 15
Constraints:
- The given dates are valid dates between the years
1971and2100.
My answer:
import time class Solution: def daysBetweenDates(self, date1: str, date2: str) -> int: time1 = time.mktime(time.strptime(date1,'%Y-%m-%d')) time2 = time.mktime(time.strptime(date2,'%Y-%m-%d')) result = abs(int((time2 - time1)/(24*60*60))) return result
看到题解的另一种方法：
from datetime import datetime class Solution: def daysBetweenDates(self, date1: str, date2: str) -> int: date1 = datetime.strptime(date1,'%Y-%m-%d') date2 = datetime.strptime(date2,'%Y-%m-%d') res = abs((date1 - date2).days) return res 作者：z1m 链接：https://leetcode-cn.com/problems/number-of-days-between-two-dates/solution/pythonshi-yong-ku-by-z1m/ 来源：力扣（LeetCode） 著作权归作者所有。商业转载请联系作者获得授权，非商业转载请注明出处。
