我不知道為什么我不斷收到錯誤 'str' has not attribute 'message'

Question

from plyer import notifications

class Reminder():
    def __init__(self,message = None):

        if not message:
            message = input("Please enter the message: ")

        self.message = message
        print(self.message)

    def sendNotification(self):
        print(self.message)
        notification.notify(title = "Python reminder", message = self.message, app_name = "Python reminder program",app_icon = "",timeout = 10,ticker = "this is ticker thing")

    def getTime(self):
        pass



Reminder.sendNotification("message")

我得到的錯誤如下：

回溯（最近一次通話最后）：文件“c:/Users/yomamahahaha/Desktop/oooohackrrr/actualprograms/python/Reminders/reminder.py”，第 28 行，在 Reminder.sendNotification("kek") 文件“c:/用戶/yomamahahaha/Desktop/oooohackrrr/actual programs/python/Reminders/reminder.py"，第 20 行，在 sendNotification print(self.message) AttributeError: 'str' object has no attribute 'message'

Answer 1

您不創建 Reminder 的實例

所以當你打電話時

Reminder.sendNotification("message")

您在這里將 'self' 設置為 "message"：然后調用"message".message ，它不存在

def sendNotification(self):
    print(self.message)

我想你的意思是

myReminder = Reminder("Message")
myReminder.sendNotification()
