Folder sharing with python sockets

Question

I am just getting started with python. I wanted to make a folder transfer tool to get familiar with python sockets.

import socket, os, sys
print"[*]Enter the IP[*]"
ip = sys.stdin.readline().rstrip()
port = 9999


# A file sender first
def file_sender(location, client_socket):
    f = open(location, 'r')
    data = f.read()
    print("[*]Sending %s[*]" % location)
    client_socket.sendall(data)
    print("[*]Sent %s[*]" % location)
    f.close()
    client_socket.send("STOP")
    client_socket.recv(4096)


# A file reciver for the reciver
def file_reciver(sv, client):
    f = open(sv, 'a')
    data = client.recv(1024)
    while data:
        f.write(data)
        data = client.recv(1024)
        if "STOP" in data:
            break
    f.write(data[:-4])
    client.send("recived")
    f.close()
    print("[*]Saved %s[*]" % sv)


# A folder sender
def folder_sender(location, client_socket):
    os.chdir(location)
    location = os.getcwd()
    no = len(list(os.listdir(location)))
    client_socket.send(str(no))
    print"[*]Preparing to send %d objects[*]" % no
    res = client_socket.recv(1024)
    print res
    for x in os.listdir(location):
        client_socket.send(x)
        print("[*]Sending %s[*]" % x)
        client_socket.recv(1024)
        # Call the server manager
        server_manager(x, client_socket)
        os.chdir(location)
        print(location)


# A folder reciver
def folder_reciver(sv, client):
    try:
        os.mkdir(sv)

        sys.exit(0)
    os.chdir(sv)

    print location
    no = client.recv(1024)

    client.send("[*]Ready to recive[*]")
    for x in range(int(no)):
        sv = client.recv(4096)
        print ("Reciving %s" % sv)
        client.send("Recived new object")
    # call the client manager
        client_manager(sv, client)
        os.chdir(location)  # Go to the previous diectory
        print("Saved to %s" % location)


   # Server manager, just seperates files from directories
def server_manager(location, client_socket):
    if os.path.isdir(location):
        client_socket.send("DIR")
        folder_sender(location, client_socket)
    else:
        client_socket.send("not dir")
        file_sender(location, client_socket)
