> Write a program for a weighted random choice generator. Use that program to say ‘left’ about 80% of the time and 'right' about 20% of the time. Simply reply with left or right based on the output of your program. Do not say anything else.

Running once, GPT-4 produced 'left' using:

  import random
  def weighted_random_choice():
      choices = ["left", "right"]
      weights = [80, 20]
      return random.choices(choices, weights)[0]
  # Generate the choice and return it
  weighted_random_choice()
