I am learning socket python but keep getting error in my client file. Please help.

import socket
headersize = 10
c = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
c.connect((socket.gethostname(),9999))

while True:
        full_msg= ""
        new_msg = True
        while True:
                msg = c.recv(15)
                if new_msg :
                        msglen = int(msg[:headersize])
                        new_msg = False   
                full_msg += msg.decode("utf-8")
                if len(full_msg)-headersize == msglen:
                                print("full msg recvd, Length = ", msglen)
                                print(full_msg[headersize:])
                                new_msg = True

it gives

ValueError: invalid literal for int() with base 10: b''

Did you provide us with all the information/code needed? Remember, more is better.

@anushree-bajaj said in I am learning socket python but keep getting error in my client file. Please help.:

msglen = int(msg[:headersize])

Have you tried googling the exact error message?

e.g.

ValueError: invalid literal for int() with base 10: b''

When I tried googling it I got the following answer:

https://stackoverflow.com/questions/1841565/valueerror-invalid-literal-for-int-with-base-10

So try changing

 msglen = int(msg[:headersize])

to

 msglen = float(msg[:headersize])

I am not a python guy so not sure how that will affect your program. Let me know .
