AttributeError： 'mainscreen'オブジェクトに属性 '属性'がありません

Question

私を解決に導くことができますか？これは私自身では解決できません。

AttributeErrorが表示されます： 'mainscreen'オブジェクトに属性 '属性'がありません ボタンを押してフルスクリーンに切り替えると、オブジェクトが表示されます。あなたの助け

if __name__ == '__main__': 
root = tkinter.Tk() 
win = mainscreen(root) 
#win.read_every_second() 
root.mainloop() 

ため THX私は（win.read_every_secondを実行したい場合は）私はエラーを取得：私が使用するように言われた割り当て

前に参照のローカル変数 'readoneortwo'：

UnboundLocalErrorをオブジェクト指向とクラスなので、グローバル変数は必要ありませんが、私はそうですね??

def toggle_fullscreen(self, event=None): 
    self.state = not self.state # Just toggling the boolean 
    if self.state: 
     self.button["text"]="No Fullscreen" 
    else: 
     self.button["text"]="Fullscreen" 

    self.master.attributes("-fullscreen", self.state) 

    return "break"  

をと（master.stateから）self.stateへの変更に気づく：次のようにこの問題を変更toggle_fullscreenを解決するために

。 「（ `self.attributes：`、まだ底には `self`を使用 - （偽、 "フルスクリーン"）I was told to use object oriented and class so I do not need global variables , but it seems I do??上部に

Using class you don't need global variables as long as you use the syntax self.someVariable = someValue. Every function of the class gets self passed as its first parameter making all the self.someVariable variables defined within the class available from within the function (as if they were "global").
