Pythonで module 'XXX' has no attribute 'XXX' が出た時の解決方法

プログラムを実行するとエラーが出た。

Traceback (most recent call last):
  File "xxx.py", line 1, in <module>
    import xxx
  File "/Users/tonosamart/xxx.py", line 4, in <module>
    def zzz(arg: xxx.yyy):
AttributeError: module 'yyy' has no attribute 'xxx'

なんかよくわかんないけど、import失敗してる感じ?

importの指定と同じファイル名のプログラムがあると、そっちを読みに行ってしまうのが原因><
他の言語と違い、ファイル名=クラス名にできないのめんどい

はまったのでメモ
