我可以传入一个列表作为 random.choices() 的权重参数吗

Question

I am trying to use the random.choices method with two lists: names and values. The values list is the weights.

I am calling the method by doing

random.choices(names, weights = values, k = 1)

The error I am receiving is

ValueError: The number of weights does not match the population

Can I not use a list as a parameter for the weights? If I can pass in a list in for the population (names), why can't I pass in a list for the weights?

Answer 1

Because I was reading in my data using pandas DataFrame functions, I was trying to pass DataFrame type data into random.choices which it did not like. I converted the data to lists and it worked.
