mining algorithms, data modeling, and so on, as long as it is more than m of data, R is very difficult to do, But Python is basically competent. Add: Python has a dedicated data analysis package

first, the initial knowledge of pandas Pandas is a very useful library based on NumPy, which has two unique basic data Structures series (one-dimensional) and dataframe (two-dimensional) that make data operations simpler. Although pandas has two

own nested list (nested list structure) structure, which is also useful for representing matrices (matrix). It is said that NumPy Python is the equivalent of becoming a free, more powerful MATLAB system.It is fast and powerful, it can support linear algebra operation, Fourier transform, random number generation and so on all kinds of mathematical meta-calculation.Official website: http://www.numpy.org/4.

Basic data types have objects (dictionaries), arrays (lists), strings, numeric values, Booleans, and null.

First set up the basic environment, assuming there is already a Python operating environment. Then need to install some common basic library, such as NumPy, scipy for numerical calculation, pandas for data analysis, Matplotlib/bokeh/seaborn for data visualization. And then o
