Thank you very much, GrandFather. I'll pay close attention to all points you mentioned.

Redundant comments are result of my code writing process. I first write down the comments to have them as instructions to myself when implementing the algorithm. I should have removed or modified them as such they are used appropriately.

Thank you once again. I have just begun writing small scripts to help me with my research. And I do enjoy a lot writing codes. I hope to improve my programming skills for the sake of both increasing productivity and fun! :)
