How to make a random selection in python, but with a certain probability?

Question

Python

Hello.
There is a list: list = [q1, q2, q3]
You need to choose one value from this list (of type random.choice(list), but with different probabilities for selection. For example, with probabilities:
q1 = 0.2
q2 = 0.3
q3 = 0.5
Is it possible, and if so, how can it be done?

Answer 1

There is also random.choices. The weights parameter specifies the weights of each value.

values = [q1, q2, q3]
data = random.choices(values, weights=[0.2, 0.3, 0.5], k=1000)
