使用不同的模块＆＃x2b;包装和计数

Question

是的。

我需要定义两个变量：

throw_yut1（），它们分别随机选择'배'或'등'，分别为60％和40％。

打印4的throw_yut4（）来自throw_yut1（），例如'배등배배'或'배배배배'等

import random

random.seed(10)

def throw_yut1():
    if random.random() <= 0.6 :
        return '배'
    else:
        return '등'
        

def throw_yut4():
    result = ''

    for i in range(4):
        result = result + throw_yut1()
    
    return result

。main.py是以下内容。

在这里，我需要重复throw_yut4 1000次，并打印获取if语句中列出的每个变量的值和百分比。

import yut

counts = {}

for i in range(1000):
   
    result = yut.throw_yut4

    back = yut.throw_yut4().count('등') 
    belly = yut.throw_yut4().count('배')

    if back == 3 and belly == 1:
        counts['도'] = counts.get('도', 0) + 1
    elif back == 2 and belly == 2:
        counts['개'] = counts.get('개', 0) + 1
    elif back == 1 and belly == 3:
        counts['걸'] = counts.get('걸', 0) + 1
    elif back == 0 and belly == 4:
        counts['윷'] = counts.get('윷', 0) + 1
    elif back == 4 and belly == 0:
        counts['모'] = counts.get('모', 0) + 1


for key in ['도','개','걸','윷','모']:
    print(f'{key} - {counts[key]} ({counts[key] / 1000 * 100:.1f}%)')

我不断得到

도 - 33 (3.3%)
개 - 115 (11.5%)
걸 - 131 (13.1%)
윷 - 22 (2.2%)
모 - 1 (0.1%)

，但我打算得到

도 - 157 (15.7%)
개 - 333 (33.3%)
걸 - 349 (34.9%)
윷 - 135 (13.5%)
모 - 26 (2.6%)

如何解决错误？

Answer 1

我认为问题在于代码的这一部分：

for i in range(1000):
    result = yut.throw_yut4

    back = yut.throw_yut4().count('등') 
    belly = yut.throw_yut4().count('배')

似乎应该是：

for i in range(1000):
    result = yut.throw_yut4()

    back = result.count('등') 
    belly = result.count('배')

否则您将从独立yut.throw_yut4（）呼叫中倒数/腹部，因此某些未手持（可能是意外）的结果是可能像背部= 4 and belly = 4 ...这就是为什么您计算的总数小于1000和100％

Answer 2

看来您的计数字典并没有填充1000个元素。这可能是因为您正在调用yut.throw_yut4（）两次，这给出了不同的结果，因此您的条件检查都没有通过。

反试试：

result = yut.throw_yut4()
back = result.count('등')
belly = result.count('등')
