Hola tengo un error de python que me dice que mi arreglo esta fuera de rango, quisiera saber su opinion, saludos

from socket import *
from sys import *
import time


if (len(argv) > 2):
print("Error en argumentos")
exit(1)

HOST = '127.0.0.1'
PUERTO = int(argv[1])

s = socket(AF_INET, SOCK_STREAM)
s.bind((HOST, PUERTO))
s.listen(1)

while True:                     
(conn, addr) = s.accept() 
datos = conn.recv(1024)
if not datos: break      
datos.decode()
tservidor = time.time()
respuesta="*"
print ("Hora del servidor: %f " %  tservidor) 
conn.send(respuesta.encode()) 
conn.close()             


ERROR : 

  PUERTO = int(argv[1])
 IndexError: list index out of range

intente cambiando valores en argv pero de todos modos me dice que el lugar es nulo,

I have an error with the range of the list, I would like to know your opinion, try to change values in ARGV but anyway I have error executing

My command to execute the script is "servidor.py 5000"

Answer 1

Your error is because you never passed an argument to the command-line. argv[1] means nothing as a result.
