Question

"""
需要计算出某个月内星期几有几天，输入（年份，weekday）
weekday是指0-6，0代表星期一，6代表星期日，
求结果，运行后总抱怨
TypeError: monthdays2calendar() missing 1 required positional argument: 'month'
问题出在哪里？

Answer 1

用下面的

import calendar
class MyCalendar(calendar.Calendar):
    def __init__(self,month):
        self.__month=month
        self.__count=0
        super().__init__()##要初始化基类
    def count_weekday_in_year(self,year,weekday):
        self.__year=year
        self.__weekday=weekday
        
        #通过类名称调用需要传入self对象，或者改为self.monthdays2calendar(self.__year,self.__month):，通过实例调用
        for weekdays in MyCalendar.monthdays2calendar(self,self.__year,self.__month):
            for date in weekdays:#monthdays2calendar返回的是七个元组的列表，其中每个元组都由日期和星期几组成。所以还得遍历一次
                if date[0]!=0 and date[1]==self.__weekday:#注意不是本月的日期为0
                    self.__count+=1
        return self.__count
 
object1=MyCalendar(6)
print('2022-6星期一天数：')
print(object1.count_weekday_in_year(2022,0))


object1=MyCalendar(5)
print('2022-5星期一天数：')
print(object1.count_weekday_in_year(2022,0))
