Question

我必须仔细检查一个单词的每个发音，这些单词都这样存储：每个单词都在字典中（以下称为wordAndPron），并且该词典中的每个单词都有多个发音作为列表存储。

{ 'RECORD' : 

[ ['R', 'AH0', 'K', 'AO1', 'R', 'D'], 

['R', 'EH1', 'K', 'ER0', 'D'], 

['R', 'IH0', 'K', 'AO1', 'R', 'D']]

}

{ 'MORTGAGE' :

[ ['M', 'AO1', 'R', 'G', 'AH0', 'JH'],

['M', 'AO1', 'R', 'G', 'IH0', 'JH']]

}

如何访问每个列表的元素？那么每个音素（例如“ R”和“ AH0”）将处于什么位置？

我将使用for循环来比较音素（找到押韵的单词），但是我不确定该怎么做。

def primary_stress_position(wordAndPron):
        stress = ''
        stressedPosition = 0
        phoneme = 0
        for phoneme in wordAndPron.values():   # <<< Problem area
                if phoneme.endswith('1'):
                        stress = phoneme
                        stressedPosition = position
                position += 1
        return stress, stressedPosition

如果这是一个非常明显/简单的问题，我深表歉意，但是我只是从Java启动Python，并且只选了另外一个编程类！

这是课堂作业。我不是问如何编写整个程序，而只是问如何访问各个元素。

Answer 1

由于wordAndPron字典的唯一值是列表列表，因此可以使用嵌套的for循环来访问其中的音素。而且，由于每个单词有多个发音，因此，您应该使函数yield成为发现对象，以便调用者可以从列表中获取给定单词的所有发音，而不是只返回列表中第一个发音的重读音素。生成器：

def primary_stress_position(wordAndPron):
    for entry in wordAndPron.values()[0]:
        for pron in entry:
            stress = ''
            stressedPosition = None
            position = 0
            for phoneme in pron:
                if phoneme.endswith('1'):
                    stress = phoneme
                    stressedPosition = position
                    break
                position += 1
            yield stress, stressedPosition

Answer 2

将所有单词放在一个字典中。访问值和部分值，如下所示。

>>> d = {
'RECORD' :
[ ['R', 'AH0', 'K', 'AO1', 'R', 'D'],
['R', 'EH1', 'K', 'ER0', 'D'],
['R', 'IH0', 'K', 'AO1', 'R', 'D']],
'MORTGAGE' :
[ ['M', 'AO1', 'R', 'G', 'AH0', 'JH'],
['M', 'AO1', 'R', 'G', 'IH0', 'JH']]
}
>>> d['RECORD']
[['R', 'AH0', 'K', 'AO1', 'R', 'D'], ['R', 'EH1', 'K', 'ER0', 'D'], ['R', 'IH0', 'K', 'AO1', 'R', 'D']]
>>> d['RECORD'][0]
['R', 'AH0', 'K', 'AO1', 'R', 'D']
>>> d['RECORD'][0][0]
'R'
>>>

我不清楚您要在功能中做什么，所以我不能说如何修改它。

Answer 3

要访问字典中列表列表的元素，您只需使用三个for循环，这很简单，此代码不言自明：

d = { 'RECORD' : 

[ ['R', 'AH0', 'K', 'AO1', 'R', 'D'], 

['R', 'EH1', 'K', 'ER0', 'D'], 

['R', 'IH0', 'K', 'AO1', 'R', 'D']]

, 
 'MORTGAGE' :

[ ['M', 'AO1', 'R', 'G', 'AH0', 'JH'],

['M', 'AO1', 'R', 'G', 'IH0', 'JH']]

}


for outter_list in d.values():
    print(f'the outter_list now is: {outter_list} \n')
    for inner_list in outter_list:
        print(f'the inner_list now is: {inner_list}')
        for element in inner_list:
            print(f'element: {element}  from current innerlist: {inner_list}')
        print('\n')
    print('--------------------------------------------')

输出：

the outter_list now is: [['R', 'AH0', 'K', 'AO1', 'R', 'D'], ['R', 'EH1', 'K', 'ER0', 'D'], ['R', 'IH0', 'K', 'AO1', 'R', 'D']]
