Question

我有2个班级：

schedule_GUI负责创建和填充默认值（从csv文件中读取）。
run_schedule负责根据时间表打开/关闭物理交换机。

schedule_GUI

run_schedule是__init__类的主人，可以共享csv文件数据（以及其他内容）。

class run_schedule():

    def __init__(self,master):
        self.master = master
        self.sch_file = master.sch_file  #### sch.file is retrieved from master
        self.continue_task = master.continue_task
        self.tasks_total = master.tasks_total
        self.loop()

如您所见，在下面的代码中，我可以在不同的标签中有多个日程表

now-可以使用GUI更新计划并保存csv文件（schedule_GUI的一部分），但是当它发生时，它不会更新sch__file中的run_schedule。

问题：主人如何更新其孩子？

init_parameters()

##Initialize GUI
root = Tk()
root.title("Advanced Schedualer")

note = tkinter.ttk.Notebook(root)
tab1 = tkinter.ttk.Frame(note)#,height=40)
tab2 = tkinter.ttk.Frame(note)
note.add(tab1, text = "Tab One", compound=TOP)
note.add(tab2, text = "Tab Two")
note.grid()

#Create GUI in TAB@
gui1 = schedule_GUI(tab1, num_switches)
gui2 = schedule_GUI(tab2, num_switches)

#Run Loop Shedules
loop1 = run_schedule(gui1)
loop2 = run_schedule(gui2)

root.mainloop()

举一个例子，我编写了这段代码来演示不同类（内部和外部）之间的传递值：

class A:
  class C:
    def __init__(self, master, v, i):
        self.x = v + i
        print("C variable was created")
        print("in C Class, and my master is:", master.firstname)
        self.CB = B(master) # create B Class var and passing A Class as Master

    def print_c(self):
        print("running function print_c inside Class C", self.x)

def __init__(self, first, last, birthday, *args):
    print("A class variable was created")
    self.firstname = first
    self.lastname = last
    self.bday = birthday
    #self.email()
    self.c1 = self.C(self, *args) #Create C Class variable

def email(self):
    def doit(arg1):
        print("this is value inside", arg1)

    print(self.firstname + '.' + self.lastname + '@' + 'gmail.com')
    doit(self.bday)
    print("this is value outside", self.bday)

class B:
def __init__(self, master):
    print("B Class created, inheret A Class parameters via a C Class:", master.firstname, master.lastname)



#running script :

a1 = A("Jhon", 'Doe', '13/12/1985', 11, 12) # create a1- an A Class variable with parameters
print("My email value from A Class:", a1.email()) # calling methon "email" belongs to a1
a1.c1.print_c() # calling c1 variable, part of a1 variable declared earlier

在类内外传递参数值
