Python Random Number Module Tutorial With Example 27 Apr 2019 Python random module has various functions to accomplish all the above tasks. We will see how to use the Randomly select an item from a List random.choices(population, weights=None, *, cum_weights=None, k=1).

## weights: Optional. A list were you can weigh the possibility for each value. Default None: cum_weights: Optional. A list were you can weigh the possibility for each value, only this time the possibility is accumulated. Example: normal weights list: [2, 1, 1] is the same as this cum_weights list; [2, 3, 4]. Default None: k: Optional.
