Question

 can anyone fix this code??it has a few errors at runtime in java.   def simulate_prizedoor(nsim):   return np.random.random_integers(0, high=2, size=nsim) 

 def simulate_guess(nsim):   return np.zeros(nsim, dtype=np.int) 

 def goat_door(prizedoors, guesses):      #strategy: generate random answers, and     #keep updating until they satisfy the rule     #that they aren't a prizedoor or a guess     result = np.random.randint(0, 3, prizedoors.size)     while True:         bad = (result == prizedoors) | (result == guesses)         if not bad.any():             return result         result[bad] = np.random.randint(0, 3, bad.sum())  # print goat_door(simulate_prizedoor(10), simulate_guess(10)) 

 def switch_guess(guesses, goatdoors):      #strategy: generate random answers, and     #keep updating until they satisfy the rule     #that they aren't the original guess or a goat door     result = np.random.randint(0, 3, guesses.size)     while True:         bad = (result == guesses) | (result == goatdoors)         if not bad.any():             return result         result[bad] = np.random.randint(0, 3, bad.sum())   #prize = simulate_prizedoor(10) #guess = simulate_guess(10) #print guess #print prize #goat = goat_door(prize, guess) #print goat #switch = switch_guess(guess, goat) #print switch 

 def win_percentage(guesses, prizedoors):     return (guesses == prizedoors).mean()*100  # prize = simulate_prizedoor(10) # guess = simulate_guess(10) # print guess # print prize # win_percentage(guess, prize) 

 nsim = 10000  #keep guesses print "Win percentage when keeping original door" print win_percentage(simulate_prizedoor(nsim), simulate_guess(nsim))  #switch pd = simulate_prizedoor(nsim) guess = simulate_guess(nsim) goats = goat_door(pd, guess) guess = switch_guess(guess, goats) print "Win percentage when switching doors" print win_percentage(pd, guess).mean
