As always, Python offers several quick solutions to this problem. However, before we get to those, I want to actually examine cloning from a beginner’s perspective. In other words, let’s skip the API for now and try to implement our own cloning function:def clone(my_list): my_list_...
In this case, we have to make adeep copyto clone all inner elements, too. You can learn more aboutShallow vs. Deep Copying in Python in this article. Usecopy.deepcopy()to clone a List and all its elements¶ To make a full clone of the List and all its inner elements, we have t...
copy()函数是Python中的一个内置函数,用于创建一个对象的浅拷贝。浅拷贝是指创建一个新的对象,但是该对象的元素仍然是原始对象的引用。换句话说,浅拷贝只复制了对象的引用,而不是对象本身。 co...

python中没有模块 试试看:pip install wikipedia Copy EventListener 您可以创建一系列用于处理传入消息的函数: let websocketconst websocketConnect = { conn: null, messageFunctions: [], start: function () { this.conn = new WebSocket('wss://...') this.conn.onmessage = (e) => { for (const...
代码中声明了一个list,将list作为参数传入了function1()中,在function1()中对list进行了del()即删除了一个元素。 而function2()也把list作为参数传入使用,在调用完function1()之后再调用function2()就出现了问题,list中的值已经被改变了,就出现了bug。
