Question

Please use Python programming language to write a client program and a server program, so that these two programs communicate through a TCP connection based on the following scenario:

1. Both of the client program and the server program are running on the same localhost.
2. The client program prompts the user to enter the radius of a circle and pass it to the server program.
3. The server program computes the area of this circle and passes it to the client program.
4. The client program displays the area on the screen

Answer 1

CLIENT.py

from socket import *
s=socket(AF_INET, SOCK_STREAM)
s.connect(("localhost",8000))
r=s.recv(1024)
a=input(r)
s.send(bytes(str(a), 'utf8'))
area=s.recv(1024)
AREA=area.decode('utf8')
print("Area of Circle is:",AREA)

---------------------------------------------------------------------------------------

SERVER.py

from socket import *
s=socket(AF_INET, SOCK_STREAM)
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
s.bind(("", 8000))
s.listen(5)
c, a=s.accept()
c.send(bytes("Enter Radius",'utf8'))
m=c.recv(1024)
R=m.decode('utf8')
radi=int(R)
area=radi*radi*3.14
c.send(bytes(str(area),'utf8'))

Instructions-

1-First run the server.py (I did using command prompt).

2-Then run client.py. (usiing command prompt)

3-Screenshot is shared of rummimg code.

4-If getting an error because of ports than change ports.
