自己は定義されていませんか？

Question

私はTkinterの学習練習として基本的な学習用時計を作ろうとしていますが、自己が定義されていないと言って実行しようとするとエラーが発生します。ここにエラーメッセージがあります。ここで

Traceback (most recent call last): 
    File "productivityclock.py", line 6, in <module> 
     class gui(object): 
    File "productivityclock.py", line 113, in gui 
     while 0 < self.z: 
NameError: name 'self' is not defined 

は私のコードで誰かが私を助けることができれば、私は本当に感謝、感謝

Answer 1

はい、ライン113で、while 0 < self.z:は適切にインデントではなく、その下のすべての行。
