For a long, long time, I have been an enthusiast of Python programming language. I am embarrassed to say that I have been trying to learn it fully for the past 10 or so years. In this much time with proper focus and dedication, I would have been a guru. But here I am, still a novice. But that's beside the point.
Now that summer vacation is here, I have decided to teach my kids Python programming as much as I know. I want to show them the path and take them with me as far as I can go and then I hope they will go further from there. While Some time ago (maybe a couple of years ago) I had given myself a challenge to create a program that I had no source or coaching. So I had decided to create a game in Python. I chose the simple game of Rock, Paper, Scissors. Over time, I changed computers and somehow I lost the source code of the program.
When my daughter started learning, she reminded me of the program and wanted to play the game. So I got started to write the program again. I'm happy to report that I have successfully re-written program. I'm sure there is a lot of scope of improvement in the coding style, code, and overall structure. But I am just starting and hope to improve. I'm posting the source code of my program and I will welcome all constructive criticism of the code and suggestions for improvement.

Note: The indentation of the code is lost.
To do: Create a GUI interface for the program if I can.
