That, plus the simple fact that Python is the main language for **Data Science**, Machine Learning and especially Deep Learning, make FastAPI a very good match for Data Science / Machine Learning web APIs and applications (among many others).

## Nơi các Gói được Cài đặt

Khi bạn cài đặt Python, nó sẽ tạo ra một vài thư mục và tệp trong máy tính của bạn.

Một vài thư mục này là những thư mục chịu trách nhiệm có tất cả các gói bạn cài đặt.

Khi bạn chạy:

<div class="termy">

```console
// Đừng chạy lệnh này ngay, đây chỉ là một ví dụ 🤓
$ pip install "fastapi[standard]"
---> 100%
```
