Python estadisticas

一个用于检测PHP代码安全的脚本，通过分析代码中的信息熵来识别其中所包含的危险代码，即便经过一定程度的代码混淆，依然可以检测出来(One for detecting the PHP script code security, identification the dangerous code contained therein, even after a certain degree of obfuscation, still can be detected by analyzing the information entropy code)

说明：  PSO代码，python实现，可直接调用，无bug(Python version of PSO algorithm)

说明：  基于聚类分析的商圈识别，附上完整版的代码和小论文(Cluster analysis based on the identification of business circle, attached small paper)

小甲鱼python教程第15-17讲动动手解答,按照自己理解写的，仅供参考，共同学习

说明：  倒谱分析的python程序，希望可以帮到大家(I hope the Python code of cepstrum can help you)

说明：  相机是将三维世界坐标系中的坐标点映射到二维图像平面的过程能够用一个几何过程描述，最简单模型称为针孔模型。 因为相机镜头透镜的存在，使得光线投影到成像平面过程中产生了畸变。(Camera is the process of mapping coordinate points in three-dimensional world coordinate system to two-dimensional image plane, which can be described by a geometric process. The simplest model is called pinhole model. Because of the existence of camera lens, the light rays are distorted when they are projected onto the image plane.)

说明：  python操作excel,获取行列数据，并分组统计(python process excel)
