This article mainly introduces the new python multi-inheritance algorithm C3, which requires complex algorithms. This article describes in detail the new algorithm C3, for more information, see mro (method resolution order). It is mainly used to

Mysql and Oracle use the rollup function to complete row and column statistics ??? Yesterday, I suddenly saw in a blog that Mysql also had the rollup function. The original blog post used rollup for row and column statistics. The original blog post

Question link: http://acm.hdu.edu.cn/showproblem.php? PID = 1, 2086 I think it's good to know that mathematics is not good on the Internet .... Because: AI = (Ai-1 + AI + 1)/2-ci, A1 = (A0 + A2)/2-C1; A2 = (A1 + A3)/2-C2 ,... => A1 + A2

MRO is method resolution order, which is used primarily to determine the path of a property (from which class) when multiple inheritance occurs. In the python2.2 version, the basic idea of the algorithm is to compile a list based on the inheritance
