NumPy(Numerical Python) yes Python An extended library of language , Support a large number of dimension arrays and matrix operations , In addition, it also provides a large number of mathematical function libraries for array operation .
NumPy The forerunner of Numeric The first is the Jim Hugunin Developed with other collaborators ,2005 year ,Travis Oliphant stay Numeric Another library of the same nature is combined in Numarray The characteristics of , And added other extensions and developed NumPy.NumPy Developed for open source and maintained by many collaborators .
NumPy It's a very fast math library , Mainly used for array calculation , contain ：
NumPy Usually with SciPy（Scientific Python） and Matplotlib（ Drawing library ） Use it together , This combination is widely used to replace MatLab, It's a powerful scientific computing environment , It helps us to get through Python Study data science or machine learning .
SciPy It's an open source Python Algorithm library and math toolkit .
SciPy The modules included are optimized 、 linear algebra 、 integral 、 interpolation 、 Special functions 、 The fast Fourier transform 、 Signal processing and image processing 、 Ordinary differential equation solution and other calculations commonly used in science and Engineering .
Matplotlib yes Python Programming language and its numerical mathematics expansion package NumPy The visual operation interface . It is designed to take advantage of the general GUI toolkit , Such as Tkinter, wxPython, Qt or GTK+ Provides application program interface to application program embedded drawing （API）.
There must be a certain Python Basics , At least familiar with its basic grammar , For example, data types 、 Sequence （ list 、 Dictionaries 、 Tuples 、 aggregate ）, And the choice of loop statements .
