Python 方法调用

Question

class AlarmBox(Widget):


    hour = ["12","1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11"]
    tensMin = ["0", "1", "2", "3", "4", "5"]
    onesMin = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
    day = ["AM", "PM"] 
    txt_inpt = ObjectProperty(None)


    def print1(self):
        self.txt_inpt.text("HI")

    XXXXXXX

如何在对象中调用 print1？

我在 XXXXXX 试过

1. self.print1()
2. self.print1(self)
3. 打印1(自己)
4. primt1()
5. c = AlarmBox()
6. c.print1()

在java中你可以这样做:

this.print1() 或 print1() !

Answer 1

您也可以在 python 中执行此操作，但您需要在某个时候执行您的代码:

class AlarmBox(Widget):


    hour = ["12","1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11"]
    tensMin = ["0", "1", "2", "3", "4", "5"]
    onesMin = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
    day = ["AM", "PM"] 
    txt_inpt = ObjectProperty(None)


    def print1(self):
        self.txt_inpt.text("HI")

    # XXXXXXX

    def print1_caller(self):
        self.print1()

XXXXX不是执行代码的地方，它是定义类成员变量和方法的地方。
