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.
Um dos objetivos do ambiente virtual é auxiliar no gerenciamento das dependências exigidas nos projetos. Um exemplo prático seria a necessidade de testar um código em uma versão antiga de um determinado pacote (ou biblioteca), sendo que na sua máquina esteja instalada a versão mais recente deste pacote. Para evitar algum possível conflito de versões, e possíveis danos no seu sistema operacional, é possível criar um ambiente virtual que deixará isolado os pacotes antigos necessários.
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.
Introduction Saving time for cleaning, tidying and processing data is quite useful in data science. It means that you can get more time to analyses and think about solutions. If I working Data Science with Python, usually I am using Pandas and Numpy library. It is a great library with a lot smart functions. However, sometimes I forget some functions and write my own functions to solve calculations. For practicing it is cool, but it spends some time.
Introduction I spent around 4 years working with R, and I can say that R is amazing. However, I decided to start a new stage in my professional life, and a need came, a multi proposal language. My option was Python, because It provides have data science tools, and has a huge support for others applications. After some months, studying in my free time, I would like to share some code that I learned (from several sources).
