Recently found that a lot of employers in recruiting data mining positions are required to be Java or Python. Want to ask what the role of this piece is? Do you need to learn a bit more? Mainly convenient, Python's third-party module is very rich, and the syntax is very concise, high degree of freedom, Python numpy, scipy, matplotlib module can complete all the functions of SPSS, and according to their own needs according to the custom method of cleaning data, Attribution, need to also be able to connect with SQL, do machine learning, many times the data is from the Internet crawler collection, Python has urllib module, can be very simple to complete this work, sometimes crawlers collect data to deal with some site verification code, Python has PIL module, can be easily identified, if need to do neural network, genetic algorithm, scipy can also do this work, there are decision trees with if-then such code, do clustering can not be limited to a certain number of clusters, may need to adjust according to the actual situation, K-means clustering , Dbscan clustering, and sometimes it is possible to combine two clustering methods to cluster analysis of large-scale data, which need to be self-coding to complete, in addition, based on distance classification method, there are many distance expression can be selected, such as Euclidean distance, cosine distance, Minkowski distance, city block distance, Although it is not complicated, but it is convenient to use Python programming, based on the content classification method, Python has a powerful NLTK natural language processing module, which splits, collects, classifies and counts the language phrases. It's very, very handy, as long as you know enough about Python,You find that you can use only this tool to quickly implement all of your ideas
