[Python] Some doubts in threading

Out of curiosity, I'm trying to implement a UDP (yes, no TCP) file exchange utility using Python for my Android phone & PC.

The sample code for the receiver is:

Code:

from socket import *
import sys
import select

host="0.0.0.0"
port = 9999
s = socket(AF_INET,SOCK_DGRAM)
s.bind((host,port))

addr = (host,port)
buf=1024

data,addr = s.recvfrom(buf)
print "Received File:",data.strip()
f = open(data.strip(),'wb')

data,addr = s.recvfrom(buf)
try:
    while(data):
        f.write(data)
        s.settimeout(2)
        data,addr = s.recvfrom(buf)
except timeout:
    f.close()
    s.close()
    print "File Downloaded"

The sample code for the sender is:

Code:

from socket import *
import sys

s = socket(AF_INET,SOCK_DGRAM)
host = raw_input("Enter host address:  ")
port = 9999
buf =1024
addr = (host,port)

file_name= raw_input("Enter file name:  ")

s.sendto(file_name,addr)

f=open(file_name,"rb")
data = f.read(buf)
while (data):
    if(s.sendto(data,addr)):
        print "sending ..."
        data = f.read(buf)
s.close()
f.close()

Now I want to modify the receiver part so that it is capable of receiving multiple files from different devices simultaneously. Any thought?? Threading??

Note that I have no prior knowledge in Python (in fact very little in programming ). Most of the codes are inspired by Python documentation & stackoverflow.com.

 

Bump! Anyone?
