What must you do in Python before opening a socket?1 pointopen socket_socket = trueimport tcpimport socketimport tcp-socket

Before opening a socket in Python, you need to import the socket module. Here is the step by step process:

1. First, you need to import the socket module. This is done by using the import statement in Python. The code would look like this:

import socket

2. After importing the socket module, you can then create a socket object. You can do this using the socket.socket() function. For example:

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

In this example, AF_INET is the address family for IPv4 and SOCK_STREAM is the socket type for TCP.

Please note that there is no need to import tcp or tcp-socket as these are not valid modules in Python. The socket module itself provides functionalities for different types of sockets including TCP.
