Question

For homework I am re-implementing the socket class in python. I am not however, well versed in python. I have a question on syntax.

From the python API when you define a socket you use:

import socket
mySocket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM))

However, I don’t know how to define constants that behave life AF_INET and SOCK_DGRAM.

import mySocket
mySocket = mySocket.socket(mySocket.AF_INET,mySocket.SOCK_DGRAM))

gives the following errors

Undefined variable from import: AF_INET
Undefined variable from import: SOCK_DGRAM

The mySocket class currently looks like:

class socket:
    AF_INET;
    SOCK_DGRAM;

    def socket(.....

Answer 1

You need to define the constants at module level, not in your socket class:

AF_INET = 2
SOCK_DGRAM = 2

class socket:
    def __init__(.....
