Class Python类没有按预期工作？

下面的代码给出了周日的结果0。没有工作，但周日有5个工作

sunday = workbook.sheet_by_name('Sunday')

class Day:
    def __init__(self, day):
        self.day = day

    jobs = {}
    def getjobs(self, day): #populates a dictionary with the information from an excel sheet
       for i in range(start_row,day.nrows):
          self.jobs[i-1] = [str(day.cell_value(i,0)).upper(), str(day.cell_value(i,1)).upper(), str(day.cell_value(i,2)).upper(), str(day.cell_value(i,3)).upper(), str(xlrd.xldate_as_tuple(day.cell_value(i,4),0)[3])+":"+str(xlrd.xldate_as_tuple(day.cell_value(i,4),0)[4]), str(day.cell_value(i,5)).upper(), str(day.cell_value(i,6)).upper(), str(day.cell_value(i,7)).upper(), str(day.cell_value(i,8)).upper(), str(day.cell_value(i,9)).upper(), str(day.cell_value(i,10)).upper(), str(day.cell_value(i,11)).upper(), str(day.cell_value(i,12)).upper(), str(day.cell_value(i,13)).upper(), str(day.cell_value(i,14)).upper(), str(day.cell_value(i,15)).upper(), str(day.cell_value(i,16)).upper(), str(day.cell_value(i,17)).upper(), str(day.cell_value(i,18)).upper()]

    no_jobs = len(jobs)

Sunday = Day(sunday)

print Sunday.day

Sunday.getjobs(Sunday.day)

print Sunday.jobs[1][1]

print Sunday.no_jobs

如果我这样做，这是可行的：

print len(Sunday.jobs)

我如何修改课堂，使print Sunday.no_作业产生5个？

您需要使用self关键字设置课堂日的变量属性：

或者，将“无作业”设置为属性：

    @property
    def no_jobs(self):
        return len(self.jobs)

Python和糟糕的缩进不是很好的组合。你能编辑你的问题，这样我们至少可以知道类的主体在哪里结束吗？修正你的缩进。没有任何作业具有空作业的长度。在初始化作业后放置no_jobs=lenjobs，并为它们设置正确的值，如jobs=getjobsSunday；no_jobs=lenjobs抱歉，粘贴时出错！

    @property
    def no_jobs(self):
        return len(self.jobs)
