Broken Pipes & Comparison Between send() and sendall()

Question

Hey,

1. I get this error in my program: BrokenPipeError: [Errno 32] Broken pipe
How can I fix it? what does it mean?

2. what's the difference between socket.send() and socket.sendall()?
Which one should I use? all i know is that sendall() is a higher level pythonic function.

Answer 1

2. All of them send data to the socket. Send returns the number of bytes sent. Sendall continues to send data until all data has been sent and returns None.

I can write something like sendall function. Maybe it will be useful.

def sendall(sock, data):
n = sock.send(data)
if n > 0:
return sendall(sock, data[n:])
return None

In case of most simple network applications you should use sendall.

Answer 2

1. It could mean a socket on client side is closed.

Handle the exception.
