data reading, processing, and exploration, while statsmodels more attention to statistical modeling analysis of data, which makes Python taste of the R language. Statsmodels supports data interaction with pandas, so it is combined with pandas to become a powerful data mining portfolio under Python.The installation of Statsmodels is quite simple, can be installed through PIP, and can be installed through the source code. For Windows users, the officia

From formatting expressions to methods, learn Python Now let's take a detailed description of the formatting method. Basic operations The so-called formatting method is to first create a template for the output string, and then use format to fill the template content. Copy codeThe Code is as follows:>>># Create a string template first>>> Template = "My name is {0}. My website is {1}. I am writing {2 }." >>>

I want to learn more about Python and list (1 ). In the previous study, we have learned two types of python data: int and str. I would like to emphasize my understanding of the data types. The world is composed of data, and the data may be numbers (Note: Do not confuse them. There are differences between numbers and data ), it may also be text, sound, or video. I
