获取一个文件并打乱中间的所有字母

Question

我需要拿一个文件并打乱每个单词的中间字母，但我无法打乱第一个和最后一个字母，而且我只能打乱超过 3 个字符的单词。我想如果我可以将每个单词放入它们自己的单独列表中，其中所有字母都分开，我就可以找到一种方法来打乱它们。任何帮助将不胜感激。谢谢。

Answer 1

text = "Take in a file and shuffle all the middle letters in between"

words = text.split()

def shuffle(word):
    # get your word as a list
    word = list(word)

    # perform the shuffle operation

    # return the list as a string
    word = ''.join(word)

    return word

for word in words:
    if len(word) > 3:
        print word[0] + ' ' + shuffle(word[1:-1]) + ' ' + word[-1]
    else:
        print word

故意不实现随机播放算法。

Answer 2

看看 random.shuffle。它将列表对象洗牌到适当的位置，这似乎就是您的目标。你可以做这样的事情来打乱字母

`

def scramble(word):

    output = list(word[1:-1])
    random.shuffle(output)
    output.append(word[-1])
    return word[0] + "".join(output)`

只要记住随机导入

Answer 3

#with open("words.txt",'w') as f:
#    f.write("one two three four five\nsix seven eight nine")

def get_words(f):
    for line in f:
        for word in line.split():
            yield word

import random
def shuffle_word(word):
    if len(word)>3:
        word=list(word)
        middle=word[1:-1]
        random.shuffle(middle)
        word[1:-1]=middle
        word="".join(word)
    return word

with open("words.txt") as f:
    #print list(get_words(f))
    #['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine']
    #print map(shuffle_word,get_words(f))
    #['one', 'two', 'trhee', 'four', 'fvie', 'six', 'sveen', 'eihgt', 'nnie']
    import tempfile
    with tempfile.NamedTemporaryFile(delete=False) as tmp:
        tmp.write(" ".join(map(shuffle_word,get_words(f))))
        fname=tmp.name

import shutil
shutil.move(fname,"words.txt")
