udp sockets with python

Hello, When measuring round trip time for the UDP echo client/server the C version is much faster. I was wondering if there is anything I can do to speed up. My current code for client looks like this sock=socket(AF_INET,SOCK_DGRAM) for x in range (1000): sock.sendto("foo",(server,port))

Re: List index out of range, but list has enough elements

Thank you all for your interest in my problem. As Peter pointed out, there was one row with zero elements in it and that's where my problem was (of course it was the very last row, hence my confidence I have "good" data). Have a nice one, Costin On Tue, Nov 9, 2010 at 12:02 PM, Nitin Pawar wrote

Thank you for your timely response. Yes, I am sure "i" and "j" are from the same iteration. I should point out that "i" actually has 8 elements and that str(i) gives a nice printout. On Tue, Nov 9, 2010 at 11:33 AM, Stefan Behnel wrote: > Costin Gamenț, 09.11.2010 10:24: >> >> Hi, I am trying to
