Python程序检查日期范围内的日期
给定一个日期列表和日期范围，任务是编写一个Python程序来检查给定范围内的列表中是否存在任何日期。
例子：
Input : test_list = [datetime(2019, 12, 30), datetime(2018, 4, 4), datetime(2016, 12, 21), datetime(2021, 2, 2), datetime(2020, 2, 3), datetime(2017, 1, 1)], date_strt, date_end = datetime(2019, 3, 14), datetime(2020, 1, 4)
Output : True
Explanation : 30 Dec’2019 lies in range of 14 March 2019 to 4 January 2020, hence True.
Input : test_list = [datetime(2018, 4, 4), datetime(2016, 12, 21), datetime(2021, 2, 2), datetime(2020, 2, 3), datetime(2017, 1, 1)], date_strt, date_end = datetime(2019, 3, 14), datetime(2020, 1, 4)
Output : False
Explanation : No date lies in range.
方法一：使用循环
在这里，对于每个元素，我们使用条件检查是否有任何日期落在范围内，如果找到，则返回 true。
Python3
# Python3 code to demonstrate working of
# Test for date in date range
# Using loop
from datetime import datetime
# initializing list
test_list = [datetime(2019, 12, 30), datetime(2018, 4, 4),
datetime(2016, 12, 21), datetime(2021, 2, 2),
datetime(2020, 2, 3), datetime(2017, 1, 1)]
# printing original list
print("The original list is : " + str(test_list))
# initializing date ranges
date_strt, date_end = datetime(2019, 3, 14), datetime(2020, 1, 4)
res = False
for ele in test_list:
# checking for date in range
if ele >= date_strt and ele <= date_end:
res = True
# printing result
print("Does list contain any date in range : " + str(res))Python3
# Python3 code to demonstrate working of
# Test for date in date range
# Using any()
from datetime import datetime
# initializing list
test_list = [datetime(2019, 12, 30), datetime(2018, 4, 4),
datetime(2016, 12, 21), datetime(2021, 2, 2),
datetime(2020, 2, 3), datetime(2017, 1, 1)]
# printing original list
print("The original list is : " + str(test_list))
# initializing date ranges
date_strt, date_end = datetime(2019, 3, 14), datetime(2020, 1, 4)
# any() for checking presence of any date in range
res = any(ele >= date_strt and ele <= date_end for ele in test_list)
# printing result
print("Does list contain any date in range : " + str(res))输出：
The original list is : [datetime.datetime(2019, 12, 30, 0, 0), datetime.datetime(2018, 4, 4, 0, 0), datetime.datetime(2016, 12, 21, 0, 0), datetime.datetime(2021, 2, 2, 0, 0), datetime.datetime(2020, 2, 3, 0, 0), datetime.datetime(2017, 1, 1, 0, 0)]
Does list contain any date in range : True
方法 2：使用any()
与上述方法类似，唯一的区别是 any() 用于检查范围内是否存在任何日期。

# any() for checking presence of any date in range
res = any(ele >= date_strt and ele <= date_end for ele in test_list)
# printing result
print("Does list contain any date in range : " + str(res))
输出：
The original list is : [datetime.datetime(2019, 12, 30, 0, 0), datetime.datetime(2018, 4, 4, 0, 0), datetime.datetime(2016, 12, 21, 0, 0), datetime.datetime(2021, 2, 2, 0, 0), datetime.datetime(2020, 2, 3, 0, 0), datetime.datetime(2017, 1, 1, 0, 0)]
Does list contain any date in range : True
