In the previous sections, you have seen a lot of examples already of how you can call a function. Calling a function means that you execute the function that you have defined - either directly from the Python prompt or through another function (as you will see in the section “Nested Fun...
You may come across other functions like call(), check_call(), and check_output(), but these belong to the older subprocess API from Python 3.5 and earlier. Everything these three functions do can be replicated with the newer run() function. The older API is mainly still there for backw...

类(Class): 定义:类是一个蓝图或模板,用于创建具有相同属性和方法的对象。它定义了对象的结构和行为。 创建新类:通过定义一个类,你创建了一个新的对象类型(type of object)。这意味着你可以创建该类的多个实例,每个实例都是类的一个具体化,拥有类定义的属性(attributes)和方法(methods)。
