Question

我正在使用tkinter GUI。此功能位于按钮后面。我可以调用整个函数的输出以在标签（在框架内）中显示吗？

def rules(value):
    if no_of_EG==6:
        print("Readability is EXTREMELY GOOD")
    elif no_of_EG==5:
        print("Readability is VERY GOOD")
    .
    .
    .
    // and so on many rules
rules(mapped)

tkinter代码：

leftFrame=Frame(window, bd=2, width=180, height=550)
leftFrame.pack(side=LEFT)

button5 = Button(leftFrame, text ="Rules", command=lambda:rules(mapped))

如果我这样做：

def rules(value):
    if no_of_EG==6:
        print("Readability is EXTREMELY GOOD")
        global a
        a = 'Readability is EXTREMELY GOOD'
rules(mapped)  

def MF():
    MFlabel1 = Label(bottomRightFrame, bg="black", fg="white", textvariale=a)
    MFlabel1.grid(row=1,column=0, sticky=E)

button5 = Button(leftFrame, text ="Rules", command=MF)

这是一个非常漫长的过程，因为有40多个规则。那么如何调用整个函数的输出呢？

Answer 1

使用widget.config(text=variable)或widget['text']=variable方法：

def MF():
    MFlabel1 = Label(bottomRightFrame, bg="black", fg="white", textvariale=a)
    MFlabel1.grid(row=1,column=0, sticky=E)
    rules(mapped)

def rules(value):
    if no_of_EG==6:
        print("Readability is EXTREMELY GOOD")
        global a
        a = 'Readability is EXTREMELY GOOD'
    MFlabel1['text'] = a
    #MFlabel1.config(text=a)     you can use the above line or this line.

button5 = Button(leftFrame, text ="Rules", command=MF)

在tkinter python中的标签中调用函数
