Below for you to share an article based on NUMPY.RANDOM.RANDN () and Rand () a detailed explanation, with a good reference value, I hope to be helpful to everyone. Come and see it together. There are some commonly used functions for generating random numbers in numpy , and Randn () and Rand () belong to this. Numpy.random.randn (D0, D1, ..., dn) returns one or more sample values from a standard normal dist

Baidu consulted some materials and combined with some of its own experience, adopted the following solutions:Copy codeThe Code is as follows:$ Idlist = '';For ($ I = 1; $ I If ($ I = 1 ){$ Idlist = mt_rand (3,25216 );}Else {$ Idlist = $ idlist. ','. mt_rand (3,25216 );}}$ Query = "select * from table where id in ($ idlist) LIMIT 0, 10 "; The principle is actually very simple. It is to generate a group of random IDs and then retrieve the records corresponding to this group of IDs. After such opti
