这是我的函数的代码:

def calcVowelProportion(wordList):
    """
    Calculates the proportion of vowels in each word in wordList.
    """

    VOWELS = 'aeiou'
    ratios = []

    for word in wordList:
        numVowels = 0
        for char in word:
            if char in VOWELS:
                numVowels += 1
        ratios.append(numVowels/float(len(word)))

现在,我正在使用超过87,000个单词的列表,这个算法显然非常慢.

有一个更好的方法吗？

编辑:

我测试了以下类提供的算法@ExP:

    import time

    class vowelProportions(object):
        """
        A series of methods that all calculate the vowel/word length ratio
        in a list of words.
        """

        WORDLIST_FILENAME = "words_short.txt"

        def __init__(self):
            self.wordList = self.buildWordList()
            print "Original: " + str(self.calcMeanTime(10000, self.cvpOriginal, …

0 == false并且'0' == false都'真'

然而,(true && 0)是'假',而(true && '0')'是'.

为什么？
