How to make a program on a topic?

Wondered how easy can a program becomes when you think of the program
to be giving output in your mind.

Programming in python is one of the interesting and easiest thing I have ever
encountered in my life. So a program can be made with high quality and less quantity.

1. First write an output model of your program.

2. Then think of what could be the possible way for it to be done.

3. Then make use if your programming instinct to make your program on the run.

4. If needed you can refer to a book for the functions and statements needed to do what
    you thought earlier in step 2.

5. Finally saving all see the output of your hard work in the output window.

Thank You!
