The numpy.random subclass provides many methods for random sampling. The following tabels list funtions in the module to generate random numbers. Simple random data Now I will summarize the usage of the first three funtions which I have met frequently. ...
NumPy also includes array-aware functions for creating, reshaping, concatenating and padding arrays; searching, sorting and counting data; and reading and writing files. It provides extensive support for generating pseudorandom numbers, includes an assortment of probability distributions, and performs accel...
