How we can send text file from client to server using TCP in python3.

Write TCP client and server allowing a file to be transferred to clients in 32 KiB sections. While files should be transferred successfully when running on localhost or across a local area network, packets may be lost when the network is heavily loaded or the connection requires several hops. To address the possibility of packet loss, we will switch to the TCP protocol.

Server>>>>

SectionServer.py implements a TCP variant of the application protocol, with the following additions and clarifications:

The TCP connection will be closed after responding to a LIST request.

The TCP connection will remain open after responding to SECTION requests in order to allow additional sections to be requested.

Erroneous requests will result in a response beginning with the word ERROR: followed by a human-readable string.

Client>>>>>>>

Implement a TCP version of SectionClient.py and verify that it can download a file successfully from the server.

Reliability>>>>>>>

Unfortunately, while the transport protocol may be reliable, the hosts claiming to implement the application protocol may not be. While responses to LIST requests can be trusted, requests to download sections may not always succeed. Your client should recover from these failures.
