python 調用 class 方法而不初始化 class

Question

I want to call a function from a python class but it would be necessary to initialize it so is there a way to call class methods without initializing the class. 我有一個js背景我想要的和這個類似

class foo {
  static calculate() {
    return 'bar';
  }
}

Answer 1

您可以使用@staticmethod裝飾器在 python 中定義 static 方法：

class Class:
    @staticmethod
    def method():
        print("Method called")

Class.method()
