Recently, as more and more data scientists began to use Python, I could not help but think that although they benefited from the libraries of Pandas, Scikit-learn and NumPy, they might have missed some of the older but also helpful python libraries.
In this blog post, I will recommend to you some little-known

I have used seaborn, bokeh, and ggplot databases!
Seaborn is biased towards statistical plot, especially linear plot, which is easy to use and simple. The entire syntax layer of seaborn will also be much simpler, and it looks nice to draw a picture without any modification. However, the drawing method is li

The magic of Psyco is that it only needs to invoke just two lines of code at the entrance of the code, and the performance can be increased by 40% or more, which is an instant!If your client feels your program is a bit slow, please don't rush to optimize the code, Psyco may be able to make him change his mind immediately. Psyco is a Python JIT, there are many potential to dig, if the rest of the time to optimize your performance is not much, plea

According to swig's ideas,C/C ++ is an excellent library-level code language, while Java, C #, and Python are dominant in writing interfaces.Therefore, swig allows you to call a class library written in C/C ++ in a higher-level language. Instead of a simple cross-language call, swig compiles the class library into a host language.ClassSuch a supe
Data processing is a great application of Python, while Excel is the most popular data processing software. So when it comes to data-related work with Python, it's hard to deal with Excel.If you just want to save your data as a form, you can work with it in CSV format (a comma-delimited tabular data format), which Excel supports. However, the standard Excel file (XLS/XLSX) has a more complex format and is n

First, IntroductionRequests is a Python HTTP client library, similar to URLLIB,URLLIB2, but the advantage of requests is that the use of simple, same functionality, with requests implementation of the code is much less. After all, the official documents are very straightforward to say:Python's standard library URLLIB2 provides most of the HTTP functionality needed, but the API is too counter-trivial, and a simple function requires a lot of code.Theref
