@validate_call 是一个功能强大的装饰器,用来验证函数的输入参数是否符合预期类型。例如,我们可以确保传递给函数的参数符合指定的数据类型: from pydantic import validate_call @validate_call def greet(name: str, age: int): return f"Hello {name}, you are {age} years old!" # 正确调用 print(greet("...
在不使用validate_call的情况下,虽然pycharm中会提示1类型不匹配,但是实际执行时并不会报错。 然而,我们通常是希望定义和使用要符合我们的预期,以避免不可预见的错误。 此时validate_call装饰器就可以很好的为我们实现这一需求。 from typing import Annotated from pydantic import BaseModel, Field, validate_call cl...

default_factory 希望设置字段类型,此外,如果您希望使用 validate_all 验证默认值,则pydantic需要调用default_factory,这可能会导致副作用! 3.1.14 私有模型属性 如果您需要使用从模型字段中排除的内部属性,则可以使用 PrivateAttr 来声明: from datetime import datetime from random import randint from pydantic import ...
