How to implement nc commands in python? [closed]

Question

I'm very new to development and may I know the equivalent python script for the following net cat command.

nc -v localhost 11211

#UPDATE

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
    s.connect(('localhost', 11211))
    data = s.recv(1024)
    print(s.sendall(data.encode('get STATUS_MANAGER_KEYS')))    
except:
    print('error')
finally:
    s.close()

Changed it as above but it showing an infinite execution at line data = s.recv(1024). May I know how to solve this.

You want to look into socket programming. Here's an example I found online https://steelkiwi.com/blog/working-tcp-sockets/

As you can see all netcat does is create a tcp connection to the network address and the port. It binds to it.

import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(('localhost', 11211))
s.listen(1)
conn, addr = s.accept()
while 1:
    data = conn.recv(1024)
    if not data:
        break
    conn.sendall(data)
conn.close()
