Question

def is_anagram(s1,s2): 
    L1 = list(s1)
    L2 = list(s2)

    return sorted(L1) == sorted(L2)



def read_words():
    fin = open('words.txt')


    for line in fin:
        line = fin.readline()
        word = line.strip()

        for line1 in fin:
            line1 = fin.readline()
            word1 = line1.strip()
            if is_anagram(word,word1):
                print(word, word1)
 read_words()

当我运行它时，它什么也没有显示（甚至没有错误）。我确信word.txt包含一些字谜。我不知道为什么这行不通。请有人帮忙。

words.txt看起来像这样：

aa
aah
aahed
aahing
aahs
aal
aalii
aaliis
aals
aardvark
aardvarks
aardwolf
aardwolves
aas

Answer 1

fin不是列表。每行只产生一次。您的两个循环不会独立地遍历它。

如果要多次迭代，请首先将这些行读入列表。一个列表可以重复多次。

def read_words():
    with open('words.txt') as fin:
        lines = [line.strip() for line in fin]

    for line in lines:
        for line1 in lines:
            if line!=line1 and is_anagram(line, line1):
                print(line,line1)

（这假定每个单词在文本文件中都位于单独的行上。）

为什么这个python代码不打印字谜？
