Question

我正在写一个字谜程序。用户输入他们想要的单词的长度，例如11然后我的程序将排序的单词存储在dict键中，而值是存储在我的样本输出中的字谜。我只打印具有大多数单词的最大值的值，例如在样本输出中它的3个单词。但如果还有另外一个含有3个单词的值，我希望也可以打印出来。

示例输出：仅打印：

['activations', 'cavitations', 'vacationist']

但我也想要：

['paternoster', 'penetrators', 'transportee']

代码

def main():
    wordList = readMatrix()
    sortDict = (lengthWord(wordList))
    maxSet = max(sortDict.values(), key = len)
    print(sorted(maxSet))
    for wor in sortDict.values():
        if len(maxSet) == len(sortDict.values()):
            print(sortDict.values())

def readMatrix():
    wordList = []
    strFile = open("wordsEn.txt", "r")
    lines = strFile.readlines()
    for line in lines:
        word = line.rstrip().lower()
        wordList.append(word)
    return tuple(wordList)

def lengthWord(wordList):
    lenWord = 11
    sortDict = {}
    wordList = readMatrix()
    for word in wordList:
        if len(word) == lenWord:
            sortWord = ''.join(sorted(word))
            if sortWord not in sortDict:
                sortDict[sortWord] = set()
            sortDict[sortWord].add(word)
    return sortDict



main()

Answer 1

这个怎么样？

d1 = dict()
d1[0] = 5
d1[1] = 9
d1[2] = 9
d1[3] = 4

maxValue = max(d1.values()) # figure out the max value
print( [key for key in d1 if d1[key]==maxValue] ) # for keys
print( [d1[key] for key in d1 if d1[key]==maxValue] ) # for values

使用Python 3.4.2 (v3.4.2:ab2c023a9432, Oct 6 2014, 22:16:31) [MSC v.1600 64 bit (AMD64)] on win32输出：

>>> d1 = dict()
>>> d1[0] = 5
>>> d1[1] = 9
>>> d1[2] = 9
>>> d1[3] = 4 
>>> maxValue = max(d1.values()) # figure out the max value
>>> print( [key for key in d1 if d1[key]==maxValue] ) # for keys
[1, 2]
>>> print( [d1[key] for key in d1 if d1[key]==maxValue] ) # for values
[9, 9]

Answer 2

max返回最大值，而不是项目。您可以通过执行max(d.values())找出最大值，并对每个键执行线性搜索，以查看它是否等于最大值。

Answer 3

如果我理解你，我会做类似的事情：

m = max(sortDict.values())
print [v for v in sortDict.values() if len(v) == m]

或更明确的方式

m = max(sortDict.values())
for val in sortDict.values():
    if len(val) == m:
        print val

在字典中查找具有最大长度的所有值
