After importing the socket module, we instantiate a new variable s from the class socket class. Next, we use the connect() method to make a network connection to the IP address and port. Once successfully connected, we can read and write from the socket. The recv(1024) method will read...

当数据不应该被复制时,例如因为数据太大或者函数设计需要在原地更改数据以使调用者受益时,调用list()会很糟糕。在这种情况下,像isinstance(x, abc.MutableSequence)这样的运行时检查将是一个好方法。如果你担心得到一个无限生成器——这不是一个常见问题——你可以先调用len()来检查参数。这将拒绝迭代器,同时安全...
To do that, you need to instantiate Desc like you’d do with any Python class. Note that you need to supply a concrete value for each named attribute, just like you did in your return statement. Here’s how describe() works now: Python >>> sample = [10, 2, 4, 7, 9, 3, 9...
To instantiate a client object, you'll need an endpoint and Azure roles or an API key. You can refer to the documentation for more information on supported authenticating approaches with the search service. Get an API Key An API key can be an easier approach to start with because it doesn...

最后 使用instantiate函数进行自执行 可以如下构造 b"(cos\nsystem\nX\x06\x00\x00\x00whoamio." b操作符 当栈中存在__setstate__时 会执行setstate(state) 也就是 这里我们如果自己写一个__setstate__类 构造os.system 和 whoami即可执行命令 ...
