文件。写不会写的文件，但正常的文本会-为什么会发生这种情况?

我测试了代码，当你只输入正常的文本到file.write(self.info)而不是self.info，它工作。但如果你让它是self。entry，它不会做任何事情。

    image = PhotoImage(file='C:/Users/plarkin2020334/Pictures/DQ_Logocp.png')
    def __init__(self, parent, *args, **kwargs):
        tkinter.Frame.__init__(self, parent, *args, **kwargs)
        Label(self, image=self.image).place(relx=0, rely=0, anchor=NW)
        Label(self, text="Enter any additional Instructiuons for the day:", background="#3f49e5").place(relx=.0, rely=.45)
        self.info = str()
        self.entry = tkinter.Entry(self, textvariable=self.info).place(relx=.0, rely=.51)
        Button(self, text="Add to Todays List", command=self.add_list).place(relx=.0, rely=.61)


    def add_list(self):
        file = open("List.txt", "w")
        file.write(self.info)
        file.close()```
