pygame.time.wait(10)
main()
私が実行するたびに、IDLEは「無効な構文」を2F_Rect = pygame.Rect(beyond2F_Rect.right,location_Y,location_Length,location_Width)に教えてくれます。どうやら、私が2F_Rect、2F_Text、2F_TextRectの2Fを "apple"や "b2F"（何かランダム）のように変えても、私はエラーにはなりません。誰かが私に説明することができた理由は、変数がその名前に "2F"を持っているため、構文エラーが出るのですか？「無効な構文」エラーが発生するのはなぜですか？
私はコピー＆ペーストして、ファイル全体を
を見て、あなたがコピー＆ペーストして、ファイル全体を持っていないし、それを回避する方法理由を確認するために[MCVE]読みください理由を見ることができます。現在のケースでは、この1行のPythonプログラム '2F_Rect = 'hello''を書いて、構文エラーがあることを確認し、短い完全なプログラムをコピーして貼り付けることができました。 –
