将用户指定的日期添加到现有代码

Question

我是一个但坚持能够将用户定义的日期添加到这个 Days to Go 代码。适用于嵌入的设定日期。但是不能让它与输入线一起工作。

from datetime import datetime, time

b = input
event = (input('What is the name of your event?'))  # input the name of the event
year = int(input('Enter a year'))  # input the requires year
month = int(input('Enter a month'))  # input the required month
day = int(input('Enter a day'))  # input the required day

def date_diff_in_seconds(dt2, dt1):
    timedelta = dt2 - dt1
    return timedelta.days * 24 * 3600 + timedelta.seconds


def dhms_from_seconds(seconds):
    minutes, seconds = divmod(seconds, 60)
    hours, minutes = divmod(minutes, 60)
    days, hours = divmod(hours, 24)
    return (days, hours, minutes, seconds)


# Specified date
date1 = datetime.date(b[1], b[2], b[3])

# Current date
date2 = datetime.now()

print("\n%d days, %d hours, %d minutes, %d seconds" %
      dhms_from_seconds(date_diff_in_seconds(date2, date1)))
print()

Answer 1

我认为你的问题很可能是这一行：

date1 = datetime.date(b[1],b[2],b[3])

尝试将其更改为：

date1 = datetime.date(year, month, day, 0, 0, 0)

Answer 2

首先，你用错了b=input。意思是你要用函数名b的input函数，比如event = b('what is the name of your event?').

相反，您可以在使用 input().

获取信息后将值赋给 b，例如 b = (event, year, month, day)

并且您通过 from datetime import datetime 导入了 datetime 模块，您不需要明确地说 datetime.date，只需 date。不过，这里可以使用datetime而不是date，如下：

from datetime import datetime, time

#b = input -> wrong usage
event = (input('What is the name of your event? '))  # input the name of the event
year = int(input('Enter a year '))  # input the requires year
month = int(input('Enter a month '))  # input the required month
day = int(input('Enter a day '))  # input the required day
b = (event, year, month, day) # you can assign date values to b

def date_diff_in_seconds(dt2, dt1):
    timedelta = dt2 - dt1
    return timedelta.days * 24 * 3600 + timedelta.seconds


def dhms_from_seconds(seconds):
    minutes, seconds = divmod(seconds, 60)
    hours, minutes = divmod(minutes, 60)
    days, hours = divmod(hours, 24)
    return (days, hours, minutes, seconds)


# Specified date
date1 = datetime(b[1], b[2], b[3]) # not datetime.date()

# Current date
date2 = datetime.now()

print("\n%d days, %d hours, %d minutes, %d seconds" %
      dhms_from_seconds(date_diff_in_seconds(date2, date1)))
print()

# if you want to print the event together:
print("\n%d days, %d hours, %d minutes, %d seconds left for %s" % (
            dhms_from_seconds(date_diff_in_seconds(date2, date1)) + (event,)))

结果是这样的：

What is the name of your event? birthday
Enter a year 2022
Enter a month 03
Enter a day 19

0 days, 14 hours, 40 minutes, 2 seconds
0 days, 14 hours, 40 minutes, 2 seconds left for Sunday # in case that you print the event together
