使用参数验证对自身执行CallOrder of Fake

class Fake:
    def __init__(self, value):
        self.value = value

def CallOrder(fake_obj):
    if not isinstance(fake_obj, Fake):
        raise TypeError("fake_obj must be an instance of Fake")
    if not isinstance(fake_obj.value, int):
        raise TypeError("fake_obj.value must be an integer")
    if fake_obj.value < 0:
        raise ValueError("fake_obj.value must be non-negative")
    
    # 执行订单操作
    print(f"Processing order with value: {fake_obj.value}")

# 正确的使用示例
fake = Fake(10)
CallOrder(fake)

# 错误的使用示例
try:
    fake_wrong_type = "not a Fake object"
    CallOrder(fake_wrong_type)
except TypeError as e:
    print(e)

try:
    fake_wrong_value = Fake(-5)
    CallOrder(fake_wrong_value)
except ValueError as e:
    print(e)
