CAN I PLEASE GET HELP WITH THIS? I AM WRITING CODE FOR A PYTHON CLIENT. PLEASE HELP!!!

MY CODE SO FAR

$ lightclient -5 -P -1 LOGFILE The client takes three arguments: 1. Server IP - The IP address of the server. 2. PORT - The port the server listens on. 3. log file location - Where you will keep a record of packets you received. For example: $ lightclient -5 192.168.2.1 -p 6543 -1 LOGFILE 4. The client must parse three command line arguments, server, port, and logfile. 5. The client should connect to the server on the specified port. 6. Constructs and sends a hello packet to the server. 1 Version (4 bytes) Message type (4 bytes) | Message Length (4 bytes) | | 1 Message (HELLO) 7 Docavo Sonor VERSION ACCEPTED" olco log "VERSION MISMATCH" 7. Receive reply from Server - if version is 17, log "VERSION ACCEPTED", else log - "VERSION MISMATCH" 8. If version is accepted, send a command packet. 1 Version (4 bytes) Message type (4 bytes) | Message Length (4 bytes) | 1 1 COMMAND (LIGHTON/LIGHTOFF) 9. Receive the server's reply, log the reply, send a DISCONNECT message to the server, and shutdown the socket. You can assume the server always replies with a "SUCCESS" message for this assignment. 10. Use TCPDUMP or Wireshark to capture the interactions, turn the .pcap file in with the assignment. $ lightclient -5 -P -1 LOGFILE The client takes three arguments: 1.
