python - 如何使用python中的字母列表搜索单词列表

Question

我有一个大约一百个单词的列表和一个包含八个字母的列表，我如何搜索每个字母以及单词，找出列表中字母最多的单词，然后打印该单词。

Answer 1

def searchWord(letters, word):
    count = 0
    for l in letters:
        count += word.count(l)

    return count

words = ['hello', 'world'];
letters = ['l', 'o']

currentWord  = None
currentCount = 0

for w in words:
    n = searchWord(letters, w)

    print "word:\t", w, " count:\t", n

    if n > currentCount:
        currentWord = w
        currentCount = n

print "highest word count:", currentWord

Answer 2

效率不高，但你可以这样做：

def search(test, words):
    return sorted(((sum(1 for c in word if c in test), word) for word in words),
        reverse=True)

这会给你一个排序的单词和计数列表。
