Pickle file and send via socket

[S.B]

Hello friends

Does anyone know if it's possible to pickle and un-pickle a file across a 
network socket. i.e: 
First host pickles a file object and writes the pickled file object to a client 
socket.
Second host reads the pickled file object from the server socket and un-pickles 
it.

Can anyone provide a simple code example of the client and server sides?

Thanks

Lot's of conflicting answers :-(

Can anyone provide a simple code example?

Thank you so much !
The examples are very helpful. 
What happens if I have a regular text file I want to send via the network.
Do I need to read the file and then dump it into the "stargate" file object?

finding a regular expression in a file

Hello friends.

Newb question here.
I'm trying to find an efficient way to "grep" a file with python.
The problem is that all the solutions I find on the web read a line at a time 
from the file with a "for line in" loop and check each line for the RE instead 
of sweeping through the entire file.
This looks terribly inefficient...

I can read the entire file like so:
open("/etc/passwd").read() 
and use that in an re.search - e.g:
re.search("root",open("/etc/passwd").read())
The above will work BUT it will not interpolate the "\n" as a newline and will 
just print the entire file as a long line.
So if I try to look for '^root' (line starting with root) instead of 'root' it 
will NOT work

any ideas on how to get around this?

Thanks.
