how to transfer a variable from a server to a client. python - python-2.7

Question

So I am really new to server and client code with python and I am doing this project from this book which asks me to do a couple of things. One of them is to transfer all the files so that the client can see them clearly. Here is the code.
Server:
import socket
from PIL import ImageGrab
import sys
sys.path.append(r'C:\Users\Home\Documents\python\new_project')
import pyperclip
import shutil
import glob
import subprocess
host = socket.gethostname()
port = 12346
server_socket = socket.socket()
server_socket.bind((host, port))
Server_online = True
while Server_online:
server_socket.listen(2)
client_socket, client_addr = server_socket.accept()
client_name = client_socket.recv(1024)
if client_name == "Screen Shot":
im = ImageGrab.grab()
f = open('C:\Users\Home\Documents\screen.txt')
i = int(f.read())
f.close()
im.save(r"C:\Users\Home\Documents\python\new_project\screen" + str(i) +'.jpg' )
i = i + 1
f = open('C:\Users\Home\Documents\screen.txt', 'w')
f.write(str(i))
f.close()
client_socket.send("Picture taken")
elif client_name == "Copy":
while 1:
try:
data = client_socket.recv(1024)
Copied = pyperclip.copy(data)
client_socket.send("text copied.")
break
except:
client_socket.send("Failed to copy")
elif client_name == "Paste":
pasting = pyperclip.paste()
elif client_name == "Show files":
while 1:
files = client_socket.recv(1024)
files_list = glob.glob("C\\Users\\Home\\Documents\\" + files + "\\*.*")
client_socket.send(**files_list**)
break
elif client_name == "Exit":
client_socket.sendall("Exting server...")
client_socket.close()
client_socket.close()
server_socket.close()
Client:
import socket
import time
import glob
host = socket.gethostname()
port = 12346
client_socket = socket.socket()
client_socket.connect((host, port))
client_connected = True
while client_connected:
print '''Pick What you want to do.(Screen Shot, Copy, Paste,
Show files, Open files, Copy files, Exit )'''
request = raw_input()
if request == "Screen Shot":
print "Screen shot in 5 seconds"
for i in range(5,0,-1):
print i
time.sleep(1)
client_socket.send("Screen Shot")
print client_socket.recv(1024)
elif request == "Copy":
client_socket.send("Copy")
print "what do u want to be copied:"
Copied = raw_input()
client_socket.send(Copied)
print client_socket.recv(1024)
elif request == "Exit":
client_socket.send("Exit")
print client_socket.recv(1024)
break
elif request == "Paste":
client_socket.send("Paste")
elif request == "Show files":
client_socket.send("Show files")
print "What files do you want to send?"
files = raw_input()
client_socket.send(files)
outcome = client_socket.recv(1024)
try:
for files in outcome:
print files
except:
print "no outcome"
else:
print "Not one of the requests. Enter again."
client_socket.close()
So as you can see it is really easy stuff but what i am stuck on is how to transfer the variable in the "Show files" (server) part where the server sends the client a list of the listed files. (its bloded).
If you can help me out that would be great I have been stuck on this for weeks

Well this is old. I solved this problem later on.
all you need to do is this (better to do it with the struct library):
on the server:
file_list = '\n'.join(file_list)
files_list_len = len(files_list)
client_name.send(files_list_len)
client_name.send(file_list)
client side:
recv_size = client_socket.recv(4)
files = client_socket.recv(recv_size).split("\n")
