Pickle a file over a socket in 1024 segments

[HybridAK]

So a snippet my attempted pickling server code:

 
with open(file_requested, 'rb') as temp:
     f = temp.read()
     f = dumps(f)

     # DOESN'T WORK - CAN'T READ 
     segment = f.read(BUFFER)

     self.connection_socket.send(segment)
     print('Sending file....')

     # Run while segment has binary data
     while segment:

          # DOESN'T WORK - CAN'T READ
          segment = f.read(BUFFER)
          self.connection_socket.send(segment)

A snippet my attempted pickling client code:

f = open('new_' + requested_file, 'wb')
segment = client_socket.recv(BUFFER)

# Keep track of the current size of the file as it's downloaded
current_file_size = len(segment)

# Start creating the file with the current segment
f.write(segment)

     # Run until the file is downloaded
     while current_file_size < file_size:
          segment = client_socket.recv(BUFFER)
          current_file_size += len(segment)
          f.write(segment)
# THEN UNPICKLE FILE

So, I know that I can read the parts of the pickled file as it gives me an error. Which means I have to break the file up some other way. Then, I know that my client needs to read each segment differently (maybe as a byte string) and then somehow I need to unpickle the completed file.

I'm new to Python and network programming, so it's a double whammy. Thanks for any help.

Another thought. Let's assume the following:

• I have successfully grabbed a file (image, pdf, etc) of 10000 bytes from a directory
  
• I then pickled the file (we will call it pickledFile)
  

Can someone give me basic code to send the pickled file (in chunks of 1024 bytes) over a socket connection and then basic code to receive the pickled file (in chunks of 1024 bytes) and then unpickle it?

Then I can see how it's done and modify my code to work.

i think some of the confusion for me is that I was told it is easier to pickle file and then send it as opposed to other options. Though in my original code I just read the file as binary and then sent it in chucks and had no problem.

Thanks.
