I am new to python . I am writing a simple client that send socket buff to a server. I fill buff in node.js like below,how can i do the same in python?

    var request = new Buffer(length);
    request .writeUInt32BE(command, 0);
    request .writeUInt32BE(length, 4);
    request .writeUInt32BE(seqNo, 8);

    buff = struct.pack(">III",0x123abc,0x123,123)

Looks like you are after the [`struct`](https://docs.python.org/3/library/struct.html#module-struct) module… – gboffi Jul 26 '19 at 10:17
