messenger

Environment:

• python 3.7.3
• windows (probably works for macOS as well)

How-to:

1. always run client 1 before you start client 2

Description:

Chat between client 1 and client 2 without an additional server. Every version provides a new functionality along following items:

• all within defined functions / classes (modular structure)
• just one socket in use
• "dynamic" chatting
• prevent application from crashing due an expected 'ConnectionResetError' (connection handling) in both directions

Version 6 is my final prototype (Cli-1.py/Cli-2.py) atm. In the next step I will clearly separate into server and client side within new files.
