随机选择(课堂点名器) Random-Selection 这是一个随机选择器(课堂点名器),老师可以用它随机点名一个同学在课堂上回答问题(当然有后门让它不点你的名字),或者用它来解决你的选择困难症 This is a random selector (roll call device), which can be used by teachers to choose a random classmate to answer ...
leaving the original population unchanged. The resulting list is in selection order so that all sub-slices will also be valid random samples. This allows raffle winners (the sample) to be partitioned into grand prize and second place winners (the subslices). Members of the population need not...

random.choice()function to Select a Random Element from a List in Python Use therandom.choice()function to choose a random element from a list in Python. For example, we can use it to select a random name from a list of names.
selection in the sample. To choose a sample in a range of integers, use range as an argument. This is especially fast and space efficient for sampling from a large population: sample(range(10000000), 60) seed(a=None, version=2) method of Random instance ...
img_scales (list[tuple]): Images scales for selection. Returns: (tuple, int): Returns a tuple “(img_scale, scale_dix)“, where “img_scale“ is the selected image scale and “scale_idx“ is the selected index in the given candidates. ...
