変数とすべてを正しく参照していることがほぼ確実だから、間違っていることがわかりません。クラスと関数 -
私は、関数を使うのがかなり新しく、1日前にPythonクラスを使うことを学んだばかりです。
私は、コードを実行するときに、私はこのエラーメッセージが表示されます:
line 37, in pathlist
while self.no_of_files > 0: #self.number_of_files
AttributeError: 'int' object has no attribute 'no_of_files'
私はそれがコードの私の順次ステップとは何かを持っている、またはので、私は変換したことであると推測していますコードの20行目のint()にnumfilesを入力します。
私は以下のコードを添付しました。事前のおかげで私を助けてください:)
