Random (strat, end, step), take a number every step from start to end to form an array, and then randomly take a number from the array, which is the same as random Choice (range (0,10,2)) equivalent [IN]:random. The random module has a set of methods: Method. This requires some parameters which are listed below: 1) a – 1-D array of np having samples. By default, the probability of each element in population of being extracted is the same, but it can be modified in two ways: Specifying the relative weights of each element with the weights parameter.
