Impacket is a collection of Python classes for working with network protocols. Impacket is focused on providing low-level programmatic access to the packets and for some protocols (e.g. SMB1-3 and MSRPC) the protocol implementation itself. Packets can be constructed from scratch, as well as pa...
Values can be appended to a list by calling append method on list. A method is just like a function, but it is associated with an object and can access that object when it is called. We will learn more about methods when we study classes....
