Matplotlib Brief Description: Matplotlib is a desktop drawing package for creating high-quality charts (mainly 2D). The project was launched by John Hunter in 2002 to build a MATLAB-style drawing interface for Python. If you use a Python IDE, such as Pycharm,matplotlib, you also have interactive features such as zoom and pan. It not only supports many different G

Recently doing a project, mainly based on the stock market to verify some model, see if you can do quantitative trading. So how do we get the data? Because customers do not want to spend money to buy data, can only find their own way, from Sina and Yahoo financial channel climbed to some data, but some data is difficul

Hehe, the first two sections don't seem to have much to do with Python. This section is all about code, This is my first time to write Python, a lot of places are messy, mainly to see the logical process. I've got a big head for the coded format.

The Unicode organization (the Unicode Consortium) is operated by a non-profit organization and dominates the subsequent development of Unicode, with the goal of replacing t

This article describes a project that will visualize the theme of the 911 attacks and their subsequent impact on news articles. I will introduce my starting point, realize the technical details and I think about some of the results. Brief introduction There is no more far-reaching event in modern American history than the 911 attacks, and its impact will continue in the future. From the events to the present, thousands of articles of different themes have been published. How can we use the t

Learn a word today, Python, everything is an object, objects are created based on the class.1 classes, objects, methodsRelationships before classes, objects, methods: Methods are defined in a class, and based on classes, you can create different objects that can use the corresponding methods defined in the class.2 Viewing objects, methods1) can be viewed directly from the command line as follows:You can use the type () to view a class of variables (ob
