JSON to Python Type Mapping
Type Mapping:
| JSON Type | Python Type | Example |
|---|---|---|
| string | str | "hello" |
| number (int) | int | 42 |
| number (float) | float | 3.14 |
| boolean | bool | True |
| null | None / Any | None |
| array | List[T] | List[str] |
| object | Nested Class | class Address |
Example:
Input JSON:
{
"id": 1,
"name": "John",
"is_active": true
}
Output Python:
from dataclasses import dataclass
@dataclass
class Root:
id: int
name: str
is_active: bool
