programming

Usually I need to classify some kind of data. Some weeks ago, I had a huge file with dates and precipitation, and one of the tasks was classify each day as ten-day. Thus, each month was divided in three sections as follow: from day 01 up to 10 is *ten-day 01* from day 11 up to 20 is *ten-day 02* from day 21 up to 31 is *ten-day 03* Most of time I had used loops (Python language), however this time the process took a little bit slow.

I am enthusiast programmer, thus I am no a professional. I wanna getting better and some times I write some notes to improve my English and programming skills. Certainly you will find some mistakes in the text and programming concepts in this post, I am sorry, I am trying. Lets go to what matter now! The word change is ambiguous in Python, it means that we have two distinct types of “change” in Python.
