Question

Write TCP client and server programs in Python that the client gets a set of integers and the length of the set as command line arguments. Then the client sends the set to the server. Afterward, the server computes the total, the highest number, the lowest number, and the mean (in float) of the set and sends the results to the client. Finally, the client receives the results and prints them out.

Answer 1

The Tcp client and server Python 3 code are given below. Make sure you are using python 3 and use proper indentation

In TCP client first enter siz of list then enter the numbers of list.

First start server in command line then in another command line start client with arguments

*************************tcpClient.py*********************************

import sys
import socket

argc=len(sys.argv)

if argc<2 or argc!=int(sys.argv[1])+2:
print('Insufficient arguments');
sys.exit()
sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server_address=('127.0.0.1',9876)
num=int(sys.argv[1]);
send_str=''
for i in range(2,num+2):
send_str=send_str+' '+sys.argv[i]
  
print(send_str)

sock.connect(server_address)
sock.send(send_str.encode())
data=sock.recv(1024)
print('Received Message From Server is:')

print(data)

*************************tcpServer.py***********************************

import socket

def findMinMax(list):
max=list[0]
min=list[0]
for i in range(len(list)):

return min,max

sock.bind((ip,port))
sock.listen(5)
print('Server started at '+ip+','+str(port))

while 1:
conn, addr = sock.accept()
arr=[]
message= conn.recv(1024)
if message:
message=str(message,encoding='utf_8')
#print('Received from client:'+message)
  
arr=message.split()

print(send_msg)
conn.send(send_msg.encode())
sock.close()
