Hey, you forgot useless comments for each method:

    get_field1(self) -> int:
      """
         Gets Field1.

         @rtype: int
         @return: the field1
      """
      self._field1

And use double underscores for private fields, because, you know, encapsulation.

Seriously though, in Java you don't need get*() either. Typically you either:

1. use `record` types (since Java14, 2020), or

2. use Lombok that auto-generates them [1], or

3. use Kotlin `data class`, or

4. just raw field access. I don't buy the encapsulation thing if my code is not a library for wide internet to use.
