json-schema-to-class's Introduction

json-schema-to-class

Convert JSON Schema into Python Class

Installation

Need Python 3.6+.

pip install json-schema-to-class

Usage

For example, convert tests/test_schema.json into Python class:

# generate & highlight
json-schema-to-class tests/test_schema.json --indent 2 | pygmentize

# or generate to file
json-schema-to-class tests/test_schema.json -o tests/schema_build.py

# generate code with __repr__ method
json-schema-to-class tests/test_schema.json --indent 2 --repr | pygmentize

Get tests/schema_build.py as follow:

from typing import List


class WarmUp:
    def __init__(self, values: dict = None):
        values = values if values is not None else {}
        self.start: float = values.get("start", 0.0)
        self.steps: int = values.get("steps", 0)


class LrSchedulerConfig:
    def __init__(self, values: dict = None):
        values = values if values is not None else {}
        self.lr_mode: str = values.get("lr_mode", 'cos')
        self.base_lr: float = values.get("base_lr", None)
        self.target_lr: float = values.get("target_lr", 0.0002)
        self.decay_factor: float = values.get("decay_factor", 0.1)
        self.milestones: List[float] = values.get("milestones", [0.3, 0.6, 0.9])
        self.lr_decay: float = values.get("lr_decay", 0.98)
        self.warm_up = WarmUp(values=values.get("warm_up"))


class LrSchedulerConfigs(list):
    def __init__(self, values: list = None):
        super().__init__()
        values = values if values is not None else []
        self[:] = [LrSchedulerConfig(value) for value in values]
