Python-在日期列表中找不到特定日期

Question

我有一年中所有日期的清单。我正在尝试在列表中查找今天的日期。

示例文件Calendar2020.txt

09/15/2020
09/16/2020
09/17/2020
09/18/2020
09/19/2020
09/20/2020
09/21/2020
09/22/2020
09/23/2020
09/24/2020
09/25/2020
09/26/2020
09/27/2020
09/28/2020
09/29/2020
09/30/2020
10/01/2020
10/02/2020
10/03/2020
10/04/2020
10/05/2020
10/06/2020

代码是：

calendarData = open('C:/Users/micha/source/repos/Test_Pass_Variables2Function/Calendar2020.txt').readlines()

current_time = datetime.datetime.now()
date = current_time.strftime("%m/%d/%Y")

for i in range(0,366):
    if(date==calendarData[i]):
        break
    else:
        print(i,end="  ")
        print("date", date, end=" ")
        print(calendarData[i])
        i=i+1

控制台输出

269  date 09/29/2020 09/26/2020
270  date 09/29/2020 09/27/2020
271  date 09/29/2020 09/28/2020
272  date 09/29/2020 09/29/2020
273  date 09/29/2020 09/30/2020
274  date 09/29/2020 10/01/2020
275  date 09/29/2020 10/02/2020

比较测试无效。 272行应该中断

您在calendarData中的每个条目都包含尾随换行符，因此它将永远与date值不匹配。只需删除换行符，就像这样：

for i in range(0,366):
    if(date==calendarData[i].strip('\n')):
        break
    else:
        print(i,end="  ")
        print("date", date, end=" ")
        print(calendarData[i])
        i=i+1
