在Python下，如何将一个单词，例如，“hello”，进行变种（mutate）？

Question

最近通过http://anandology.com/python-practice-book/working-with-data.html上的问题练习Python，做到章节2.6－列表第32个问题的时候，写出了以下代码，是否有更好的代码，可以解决这个问题。原问题如下：

Problem 32: Write a function mutate to compute all words generated by
a single mutation on a given word. A mutation is defined as inserting
a character, deleting a character, replacing a character, or swapping
2 consecutive characters in a string. For simplicity consider only
letters from a to z.

我的代码如下：

#coding:utf-8
def mutate(ori_word):
    result = []
    characters = [chr(w) for w in xrange(97,123)]
    split_word = [w for w in ori_word] #['h', 'e', 'l', 'l', 'o']
    for x in xrange(0,5):
        word = split_word[:]
        word.pop(x)
        result.append(''.join(word)) # delete any one of the character in "hello"
        for c in characters:
            word = split_word[:]
            word[x] = c
            result.append(''.join(word)) # replace any one of the character in "hello" by using a to z
        for y in xrange(0,5):
            word = split_word[:]
            word[x] , word[y] = word[y], word[x]
            result.append(''.join(word)) # swap two character in "hello"
    return result

word = mutate("hello")

Answer 1

목록 이해력을 더욱 활용해야 합니다

for x in xrange(0,5) 피해야 할 사항

split_word = [w for w in ori_word] str

을 통해 반복할 수 있으므로 약간 불필요합니다.
