Question

我的python脚本需要帮助。如何通过Date's课程访问我的时钟功能？

from datetime import date
from datetime import datetime

class Date(object):
    def date_today(self):
        now = date.today()
        print (now)

class Time(Date):
    pass
    def clock(self):
        hr = datetime.now()
        hr_now = hr.hour
        print (hr_now)

cr_date = Date()
print (cr_date.date_today())
print (cr_date.date_today.clock())

我收到了错误 - ＆gt; AttributeError：＆＃39;功能＆＃39;对象没有属性＆＃39; clock＆＃39;。这个错误的原因是什么？

您还可以在时间班中添加分钟，秒和其他相关功能。我希望它会有所帮助。
