Django中modelfrom、from 和 fastapi 中的 pydantic 对比?

Is there any difference between pydantic in fastapi and modelform and form in Django?

The following is my personal understanding:

If only mode and Lform are used together in the back end, it is possible to maximize the use of Lform.

Pydantic: it only does data conversion, but does data type verification in the implicit. It can be regarded as having two verification methods, but the official website only considers it as a database for data analysis.
