common libraries python data analysis


Python Why is it popular ? because Python Simple 、 Understandability 、 To use , Is a high-level programming language ; besides ,Python Provides a large number of third-party libraries , Open the box , convenient 、 free , Very suitable for work in the field of data analysis .

You know that ,Python There are lots of libraries , Very suitable for data analysis tools , So you know Python Are there any common libraries for data analysis ? These four are very important !

NumPy

yes Python The basic package of Scientific Computing , Provides fast and efficient multidimensional array objects ndarray; Functions that directly perform mathematical operations on arrays and element level calculations on arrays ; Tools for reading and writing array based data sets on hard disks ; Linear algebra operations 、 Fourier transform and random number generation .

Pandas

It can be said that it only needs to do data analysis , No one knows, no one knows , Because it plays a very important role .Pandas Libraries provide many of our functions , Fast 、 Easy to handle large structured data .

It's no exaggeration to say ,Pandas It's Jean Python A very important factor in becoming a powerful data analysis tool , Especially for the financial industry , For example, analysts of fund stocks ,Pandas It provides high performance time series function and a series of tools , It can process data freely and flexibly , Use it once and you'll fall in love with it .

Matplotlib

It's popular for charting data Python library , It goes with IPython It's better to use it in combination , Provides a very useful interactive data drawing environment .

IPython

It is Python Part of the standard toolkit for Scientific Computing , You can connect a lot of things , It's kind of like an enhanced version of Python shell.

The goal is to improve programming 、 Testing and debugging Python Code speed , A lot of cattle are using IPython, It's very convenient , When we analyze the data , It's also with this tool , And No print, Press enter to print .
