How can I get Python 3.7 new dataclass field types?

Question

Python 3.7 introduces new feature called data classes.

from dataclasses import dataclass

@dataclass
class MyClass:
    id: int = 0
    name: str = ''

When using type hints (annotation) in function parameters, you can easily get annotated types using inspect module. How can I get dataclass field types?

Answer 1

from dataclasses import dataclass

@dataclass
class MyClass:
    id: int = 0
    name: str = '' 

myclass = MyClass()

myclass.__annotations__
>> {'id': int, 'name': str}
myclass.__dataclass_fields__
>> {'id': Field(name='id',type=<class 'int'>,default=0,default_factory=<dataclasses._MISSING_TYPE object at 0x0000000004EED668>,init=True,repr=True,hash=None,compare=True,metadata=mappingproxy({}),_field_type=_FIELD),
 'name': Field(name='name',type=<class 'str'>,default='',default_factory=<dataclasses._MISSING_TYPE object at 0x0000000004EED668>,init=True,repr=True,hash=None,compare=True,metadata=mappingproxy({}),_field_type=_FIELD)}

on a side note there is also:

myclass.__dataclass_params__
>>_DataclassParams(init=True,repr=True,eq=True,order=False,unsafe_hash=False,frozen=False)
