Hi
I want to know the how we input values into the matrix (N*N size)
from keyboard in python,
Here I wrote Matrix programe in C++
This asks values from key board and print on the console N*N matrix ;
Thanks in advance

Socket programming
Hi i am learning socket programming,
client code:
import socket
client_socket=socket.socket()
server_address='192.168.2.2'
server_port= 80
print("hello")
client_socket.connect((server_address,server_port))
print("hello")
data=client_socket.recv(1024)
print(data)
client_socket.close()
server code:
import socket
server_socket=socket.socket()
server_name='192.168.2.2'
server_port= 80
server_socket.bind((server_name,server_port))
server_socket.listen(1)
while True:
print("hello")
c,address=server_socket.accept()
print("we got connection from:",address)
c.send("hello,hw ru")
c.close()
I am not getting the output, i am using windows 7 OS..
please check and give me the solution.

Client side web programming
Hi, Well the trouble is that my orkut scrapbook is flooded. So I reckoned that I'd write some sort of a script to delete the 14800 or so scraps. Now the big problem is that I don't really have too much knowledge about web programming. I have a rough idea about HTTP, HTTPS, cookies etc. but I don't really know the specifics. Question 1: Orkut seems to use a cookie to keep track of who I am. How long will this cookie be valid? Supposing I login using Mozilla and then get hold of this cookie, then use my Python script and send the same cookie whilst send a "POST" request to delete the entry, will orkut be fooled? Question 2: How do I send a specific cookie along with my request? The whole documentation for urllib2 is rather general and seems to assume thorough knowledge of how those protocols work. Question 3: Is there a simpler way? Question 4: Pointers to further information? Thanks, Pramod -- http://mail.python.org/mailman/listinfo/python-list

Luiz Geron wrote: > Maybe this will be useful to you: > http://www.python.org/pypi/mechanoid/0.6.8 Actually I found this thing when I was googling. But there isn't too much documentation, which is why I posted here. Using cookielib and urllib2, I've come up with a workable solution. Its damn slow though - which is probably orkut's fault - deletes about 10-15 scraps a minute - so to get through 14000 scraps its probably gonna take around 23 hours. Anyway, thanks a lot everybody.

My requests timed out about 5 times in that span, but its hard to say whether it was a load limiter because orkut is somewhat unreliable anyway. -- http://mail.python.org/mailman/listinfo/python-list

Query regarding support for IPv6 in python
Hello All, I have some queries related to python support for IPv6. Can you kindly clarify the doubts which I have - 1. Does python support IPv6? [128 bit IP addresses?] 2. Does it support setting of QoS flags? 3. Does it support tunneling of IPv6 on a IPv4 network? 4. If an IPv4 address is given, does it support this on a IPv6 network? If not can you kindly let me know, Are there any plans for supporting these features in future? For Example - In IPv4 we have gethostbyname() function, which is deprecated in IPv6. In IPv6, getaddrinfo() and new data structure like struct addrinfo is introduced. Is this new function getaddrinfo() of IPv6 is supported in Win32 Extensions for python.

help: Question regarding parallel communication using python
Hello, I would like from my Python application to control 2 (or more devices) using the existing port's interface in my PC,like serial (COM1) or Parallel port (lpt) or any other like PCI...etc. The control mechanism usually involves sending messages to the connected devices in parallel. For instance, I would like to send a command to a target connected on COM port and at the same time would like to read the value of a Digital multimeter over other COM port ( or may be via USB with some adapter) My Question is: - Is it possible to achieve the above in Python ? - Do we need to use any kind of Parallel processing to achieve this ? - If so, Which of the available packages (like pypar or Pydusa..etc) suits best ? Please suggest. Thank you very much in advance, With Regards, Pramod -- http://mail.python.org/mailman/listinfo/python-list
