【问题标题】：Differences between two dates in pythonpython中两个日期之间的差异
【发布时间】：2020-06-28 09:01:23
【问题描述】：

from datetime import date
import random    
earlier_date = date(2017, 6, random.randint(1, 25))    
later_date = date(2017, 6, random.randint(earlier_date.day + 1, 28))    
days_between = (later_date - earlier_date)    
print("There are",days_between,"days between", earlier_date, "and", later_date)

我的输出（完全不同）

There are 18 days, 0:00:00 days between 2017-06-01 and 2017-06-19

我想要的输出（仅限日差）

There are 3 days between 2017-06-22 and 2017-06-25

【问题讨论】：

与stackoverflow.com/questions/8258432/days-between-two-dates重复
有什么问题？你选择随机日期，你怎么能期待一个具体的结果？
您的代码非常适合我，它总是选择 2 个日期，并显示日期差异
2017-06-01 和 2017-06-19 之间有 18 天，0:00:00 天这是我得到的输出......我想要输出，正如我在问题中提到的那样
您可能第一次在帖子中告诉我们。因为我个人得到确切的日期数

【解决方案1】：

使用days_between.days 表示天数差异。我还为day 语法添加了一个 s-check

# String parts
print("There are", days_between.days, "day" + ('s' if days_between.days > 1 else '') +
      " between", earlier_date, "and", later_date)

# f-string
print(f"There are {days_between.days} day{'s' if days_between.days > 1 else ''} "
      f"between {earlier_date} and {later_date}")
