步骤1:定义一个类 首先,我们需要定义一个类,并在其中添加一个static方法。以下是示例代码: classMyClass:@staticmethoddefmy_static_method():print("This is a static method") 1. 2. 3. 4. 步骤2:在类中定义一个static方法 在上面的示例代码中,我们使用@staticmethod装饰器定义了一个
test_fuc.static_fuc(1) TestFuc.static_fuc(1) 应用 脱离了实际的应用场景,谈使用就是是耍流氓。上文介绍的"使用"仅仅展示如何定义(进入)和伪使用,真正的场景不会这样用的。 静态方法(staticmethod)和类方法(classmethod)并不常用。我喜欢在stackoverflow:What is the advantage of using static methods in Py...
可读性更好了,看到@staticmethod 后,我们就可以知道此方法是对立的,不需要依赖类的实例。 In[3]:Pizza().cookisPizza().cook Out[3]:FalseIn[4]:Pizza().mix_ingredientsisPizza.mix_ingredients Out[4]:TrueIn[5]:Pizza().mix_ingredientsisPizza().mix_ingredients Out[5]:TrueIn[6]: 1. 2. 3. ...
print("Call static method foo1()\n") @classmethod def Foo2(cls): print("Call class method foo2()") print("cls.__name__ is ",cls.__name__) A.Foo1(); A.Foo2(); 结果是: Python code Call static method foo1() Call class method foo2() cls.__name__ is A...
a.static_foo(1)A.static_foo('hi')对于静态类staticmethod，即使它是一个method，a.static_foo仅仅...
class A: @staticmethod def f1(x): print(x) A.f1(2) # 2 类.静态方法 A().f1(2) # 2 对象.静态方法 这种情况下是可以执行的,如果上述f1没有被staticmethod装饰那么就会报错!!! 通过类调用函数。同时,因为该方法被staticmethod装饰器装饰了,那么通过对象.方法 也是可以调用的。
They each return a tuple containing information to help you trace what’s going on, as well as the arguments the method received, such as self and cls. The output will help you understand which objects each of the methods can access....
A. def static_method():B. static def method():C. staticmethodD. def method() static: 相关知识点: 试题来源: 解析 C 在Python中,定义静态方法需使用@staticmethod装饰器。A选项缺少装饰器,仅为普通方法;B选项语法错误,static位于def前不符合Python语法;C选项是装饰器名称,正确使用应为@staticmethod,但题目...
Static method What about staticmethod? It's pretty similar to classmethod but doesn't take any obligatory parameters (like a class method or instance method does). Let's look at the next use case. We have a date string that we want to validate somehow. This task is also logically bound ...
elif type(i) is tuple: print("key是一个元组,对应的value:", d[i]) print(type(d[('k', '3')])) 8 如果不使用@wrapper装饰器,请在a()之前加入一句代码,达到相同的效果 def wrapper(func): def inner(*arg, **kwargs): func(*arg, **kwargs) ...
