Python 函数没有响应

Question

我是 python 新手。我有这四个相关的功能，但最后一个没有响应。

import ui as numpy


def simulate_prizedoor(nsim):
    sim=ui.random.choice(3,nsim)
    return sims

def simulate_guess(nsim):
        guesses=ui.random.choice(3,nsim)
        return guesses

def goat_door(prizedoors, guesses):


        result = ui.random.randint(0, 3, prizedoors.size)
        while True:
            bad = (result == prizedoors) | (result == guesses)
            if not bad.any():
                return result
            result[bad] = ui.random.randint(0, 3, bad.sum())

def switch_guesses(guesses, goatdoors):


            result = ui.random.randint(0, 3, guesses.size)
            while True:
                bad = (result == guesses) | (result == goatdoors)
                if not bad.any():
                    return result
                result[bad] = ui.random.randint(0, 3, bad.sum())

如您所见，第三个和第四个函数具有相同的代码。

我运行第一个和第二个函数:

a=simulate_prizedoor(4)
b=simulate_guess(4)
print(a)
[2 2 0 2]
print (b)
[2 0 0 2]

然后，我用 a 和 b 的值运行第三个函数

c=goat_door(a,b)
print(c)
[1 1 2 1]

最后，我运行了最后一个函数，但是 python 没有响应，似乎给出答案是一个无限的过程。

   switch_guess(b,c)

Answer 1

您发布的代码存在错误，无法运行。请在提问时发布未经修改的原始代码 - 您将更有可能获得建设性的反馈和好的答案。

以下是我在您发布的代码中发现的错误:

Traceback (most recent call last):
  File "montyhall.py", line 1, in <module>
    import ui as numpy
ImportError: No module named ui

我对正确行的猜测:import numpy as ui

Traceback (most recent call last):
  File "montyhall.py", line 27, in <module>
    a=simulate_prizedoor(4)
  File "montyhall.py", line 5, in simulate_prizedoor
    return sims
NameError: global name 'sims' is not defined

我对正确功能的猜测:

def simulate_prizedoor(nsim):
    sim=ui.random.choice(3,nsim)
    return sim

你的缩进也有点奇怪。

我运行的更正代码包含在下面。当我运行它时，没有任何错误，simulate_prizedoor 函数也没有陷入循环。也许您正在运行的代码存在导致问题的差异？

import numpy as ui

def simulate_prizedoor(nsim):
    sim=ui.random.choice(3,nsim)
    return sim

def simulate_guess(nsim):
    guesses=ui.random.choice(3,nsim)
    return guesses

def goat_door(prizedoors, guesses):
    result = ui.random.randint(0, 3, prizedoors.size)
    while True:
        bad = (result == prizedoors) | (result == guesses)
        if not bad.any():
            return result
        result[bad] = ui.random.randint(0, 3, bad.sum())

def switch_guesses(guesses, goatdoors):
    result = ui.random.randint(0, 3, guesses.size)
    while True:
        bad = (result == guesses) | (result == goatdoors)
        if not bad.any():
            return result
        result[bad] = ui.random.randint(0, 3, bad.sum())

a=simulate_prizedoor(4)
b=simulate_guess(4)
print(a)
print (b)
c=goat_door(a,b)
print(c)
d=switch_guesses(b,c)
print(d)
