Modulerandomin the standard Python library offers a wealth of possibilities for generating and using pseudo-random numbers, but it does not offer this specific functionality, so we must code it as a function of our own: import random def random_pick(some_list, probabilities): x = random.unifo...

Use random.choice() function to randomly select an item from a list, String, Dictionary, and set. Pick a single random number from a range
Let’s think about a simple example where we have a set of numbers contained in a list,and we would like to pick one of those numbers uniformly at random. 在本例中,我们需要使用的函数是random.choice,在括号内,我们需要一个列表。 The function we need to use in this case is random.choice...
