这个错误是因为在调用 `phone.call_by_5g(self)` 时，将 `self` 参数传递给了它，导致参数个数不匹配。可以直接调用 `super().call_by_5g()` 来避免这个问题。修改后的代码如下：

class phone:
    IMEI = None
    producer = "ITCAST"

    def call_by_5g(self):
        print("使用5g通信")

class myphone(phone):
    producer = "ITCAST2"

    def call_by_5g(self):
        print("开启cpu单核模式")
        print(f"父类的厂商是：{super().producer}")
        super().call_by_5g()
        print("关闭cpu单核模式")

phone = myphone()
phone.call_by_5g()
print(phone.producer)
