我怎样才能使这个 Python 代码不那么重复？

Question

我一直在寻找基于变量调用不同函数的方法，我想出了这个字典映射。 我想知道是否有办法以某种方式改进它并减少重复性？

 def schedule_on_monday(time):
    schedule.every().monday.at(time).do(job)
 

def schedule_on_tuesday(time):
     schedule.every().tuesday.at(time).do(job)
 

def schedule_on_wednesday(time):
    schedule.every().wednesday.at(time).do(job)


def schedule_on_thursday(time):
    schedule.every().thursday.at(time).do(job)


def schedule_on_friday(time):
    schedule.every().friday.at(time).do(job)


def schedule_on_saturday(time):
    schedule.every().saturday.at(time).do(job)


def schedule_on_sunday(time):
    schedule.every().sunday.at(time).do(job)


def schedule_tasks(day, time):
    switcher = {
        'monday': schedule_on_monday,
        'tuesday': schedule_on_tuesday,
        'wednesday': schedule_on_wednesday,
        'thursday' : schedule_on_thursday, 
        'friday' : schedule_on_friday, 
        'saturday' : schedule_on_saturday, 
        'sunday' : schedule_on_sunday
    }
    func = switcher.get(day, lambda: "Invalid")
    func(time)

Answer 1

您可以使用getattr从字符串中获取属性名称：

def schedule_tasks(day, time):
    getattr(schedule.every(), day).at(time).do(job)

Answer 2

您可以尝试使用 exec function：

def schedule_tasks(day, time):
    exec("schedule.every().{0}.at({1}).do(job)".format(day, time))
