Data analysis using Python

Data analysis using Python
 
Programming language
Python
Recently, more and more often used for data analysis, both in science and in the commercial sphere. This is facilitated by the simplicity of the language, as well as by the wide variety of open libraries.
 
In this article, we will analyze a simple example of research and classification of data using some libraries on
Python
. For the study, we need to select the data set we are interested in ( DataSet
). Various sets of Datasets can be download from the site . The DataSet is usually a file with a table in JSON or CSV format. To demonstrate the possibilities...

Universal links: the palace of the reefs

Resizing images on the site

Good afternoon. I am a developer with more than 10 years experience. In order to assess the quality of the source code of the site, not without a share of self-irony, I created a small check-list. Today I'll talk about an important point for me - images on websites. I deliberately omitted the specific technology, because this problem was encountered and is met everywhere, I would be very grateful if in the comments you will reveal your approaches using your stack of technologies, in the end we all are very similar.
