operations associated with linear algebra we can also see numpy as the replacement of matlab because numpy is mostly used along with scipy (scientific pythonand mat-plotlib (plotting libraryinstallation and execution if you are using anaconda distributionthen no need to install numpy separately as it is already installed with it you just need to import the package into your python script with the help of followingimport numpy as np on the other handif you are using standard python distribution then numpy can be installed using popular python package installerpip pip install numpy after installing numpyyou can import it into your python script as you did above for more detailed study of numpyyou can go to the link pandas it is another useful python library that makes python one of the favorite languages for data science pandas is basically used for data manipulationwrangling and analysis it was developed by wes mckinney in with the help of pandasin data processing we can accomplish the following five stepsload prepare manipulate model analyze data representation in pandas the entire representation of data in pandas is done with the help of following three data structuresseriesit is basically one-dimensional ndarray with an axis label which means it is like simple array with homogeneous data for examplethe following series is collection of integers , , , , , data frameit is the most useful data structure and used for almost all kind of data representation and manipulation in pandas it is basically two-dimensional data structure which can contain heterogeneous data generallytabular data is represented by using
