-   `C:\Program Files\Python312`
-   `C:\Windows\System32`

C'est un programme très simple.

    # If this step fails, then you should remove it and run the build manually (see below)

    # ✏️ If the Autobuild fails above, remove it and uncomment the following three lines
    #    and modify them (or add more) to build your code if your project

O programa de linha de comando chamado `fastapi` é o **FastAPI CLI**.

O FastAPI CLI recebe o caminho para o seu programa Python (por exemplo, `main.py`), detecta automaticamente a instância de `FastAPI` (comumente nomeada `app`), determina a forma correta de importação e então a serve.

Bir **Web API** için bu süreç normalde uygulamayı **uzak bir makineye** yerleştirmeyi, iyi performans, kararlılık vb. özellikler sağlayan bir **sunucu programı** ile **kullanıcılarınızın** uygulamaya etkili ve kesintisiz bir şekilde **erişebilmesini** kapsar.
