python将json实例化为class文件 写入.py文件

本文主要是介绍python将json实例化为class文件 写入.py文件，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

python将json实例化为class文件 写入.py文件create_class.py

import jsonclass Command:def handle(self, *args, **kwargs):json_file = kwargs['json_file']class_name = kwargs['class_name']output_file = kwargs['output_file']with open(json_file, 'r') as f:data = json.load(f)class_def = f"class {class_name}:\n"for key, value in data.items():if not isinstance(value, str):class_def += f"    {key} = {value}\n"else:class_def += f"    {key} = '{value}'\n"with open(output_file, 'w') as f:f.write(class_def)if __name__ == "__main__":c = Command()c.handle(json_file='config.json', class_name="TestClass", output_file='test_01.py')

config.json

{"name": "John Doe","age": 31,"is_student": false,"courses": ["Math","Physics","Chemistry","Biology"]
}

运行后即可得到
文件 test_01.py

class TestClass:name = 'John Doe'age = 31is_student = Falsecourses = ['Math', 'Physics', 'Chemistry', 'Biology']

还可以定义模版文件，然后直接写成.py文件
文件：config4_bx.py

import json# JSON 数据字符串
json_data = '''
{"name": "John Doe","age": 30,"is_student": false,"courses": ["Math", "Physics", "Chemistry"]
}
'''# 解析 JSON 数据
data = json.loads(json_data)# 定义类名
class_name = "Person"
func_name = "BYD_A88"def func1():print('111')# 生成类定义的模板
class_template = f"""
from src.common.config4_bx import func1class {class_name}:def __init__(self):
{"".join(f'        self.{k} = "{v}"\n' if isinstance(v, str) else f'        self.{k} = {v}\n' for k, v in data.items())}def __str__(self):return f"{class_name}(name={data.get('name')}, age={data.get('age')}, is_student={data.get('is_student')}, courses={data.get('courses')})"def test_{func_name}_smoke(self):func1()
"""# 写入 Python 文件
with open('test_person.py', 'w') as file:file.write(class_template)# 输出生成的类定义
print(class_template)
