Python -在一个句子中翻转每个单词的两个字符

Question

除了第一个和最后一个字符外，我的函数还随机地翻转一个单词的两个字符。我想使用这个函数来编写另一个函数build_sentence(string)，它使用我的函数翻转句子中每个单词的两个字符。函数build_sentence(string)应该返回一个字符串，其中包含scrambled(word)对每个单词的字母进行置乱的完整句子。

例如：

I dn'ot gvie a dman for a man taht can olny sepll a wrod one way. (Mrak Taiwn)

​

import random 

def scramble(word):
    i = random.randint(1, len(word) - 2)
    j = random.randint(1, len(word) - 3)
    if j >= i:
        j += 1

    if j < i:
        i, j = j, i

    return word[:i] + word[j] + word[i + 1:j] + word[i] + word[j + 1:]

def main():
    word = scramble(raw_input("Please enter a word: "))
    print (word)
    
main()

假设您对当前的单词置乱功能感到满意(只需稍加改动，这样就不会对3个或更少字母的单词产生错误)：

import random

def Scramble(word):
    if len(word) > 3:
        i = random.randint(1, len(word) - 2)
        j = random.randint(1, len(word) - 3)
        if j >= i:
            j += 1

        if j < i:
            i, j = j, i

        return word[:i] + word[j] + word[i + 1:j] + word[i] + word[j + 1:]
    else:
        return word

def ScrambleSentence(sentence):
    scrambledSentence = ""
    for word in str.split(sentence):
        print(scrambledSentence + "\n")
        scrambledSentence += Scramble(word) + " "
    return scrambledSentence.strip()

def main():
    sentence = ScrambleSentence(input("Please enter a sentence: "))
    print (sentence)

main()

你试过：

' '.join(scramble(word) for word in phrase.split(' '))
