Course Description:??The course style is easy to understand, real case actual cases. Carefully select the real data set as a case, through the Python Data Science library Numpy,pandas,matplot combined with the machine learning Library Scikit-learn to complete some of the column machine learning cases. The course is bas

FrontierThrough the previous section on the Python combat data visualization of the Pygal module (Basic) Learning, we have a preliminary understanding of the use of Pygal module, this section will be a practical project to deepen the use of Pygal module. The JSON-formatted population data can be downloaded from the Web and processed using JSON modules, and the Py

FrontierPython provides a number of modules for data visualization, including Matplotlib, Pygal. I refer to the online popular books "Python programming from the beginning to the actual combat", in the test and learning process encountered a few problems to solve, just write down this project experience, for the basic part of the Python is not detailed, mainly th

applicable to modern programming. To use variable-size, hardware-independent data types, Java and other programming languages provide a more advanced data structure: ArrayList, Vector, and other dynamic arrays. Python array Strictly speaking, Python does not have arrays in a strict sense. List can be called an array i

There are 3 built-in data structures in Python: Lists, tuples, and dictionaries. Refer to the Concise Python tutorial 1. ListA list is a data structure that handles a set of ordered items, that is, you can store a sequence of items in a list. Imagine you have a shopping list that says what you want to buy, and you can

7 Tools for Data visualization in R, Python, and JuliaLast week, some examples of creating visualizations with Htmlwidgets and R were presented. Fortunately, there is many more options available for creating nice visualizations. Tools and libraries exist for all your favorite languages. This post plans-provide a quick reference list of some of the possible options for creating

U.S. scientists announced 11th that they first detected gravitational waves last September. This discovery confirms the prophecy of the physicist Einstein 100 years ago. Announcing the discovery was the head of the laser-interferometric gravitational Wave Observatory (LIGO). The institution was born in the 90 's and has been observed for nearly 30 years by gravitational wave observations. So the amount of gravitational wave data that is observed shou
