python - 如何使用python删除单词中的空格？

Question

这是给定的输入 John play chess and l u do o. 我希望输出采用这种格式(如下所示)

John 下国际象棋和 ludo。

我已经尝试使用正则表达式来删除空格 但对我不起作用。

import re
sentence='John plays chess and l u d o'
sentence = re.sub(r"\s+", "", sentence, flags=re.UNICODE)

print(sentence)

我期望输出 John plays chess and ludo. .
但是我得到的输出是 Johnplayschessandludo

这应该有效!从本质上讲，该解决方案从句子中提取单个字符，使其成为一个单词，然后将其连接回剩余的句子。

s = 'John plays chess and l u d o'

chars = []
idx = 0

#Get the word which is divided into single characters
while idx < len(s)-1:

    #This will get the single characters around single spaces
    if s[idx-1] == ' ' and s[idx].isalpha() and s[idx+1] == ' ':
        chars.append(s[idx])

    idx+=1

#This is get the single character if it is present as the last item
if s[len(s)-2] == ' ' and s[len(s)-1].isalpha():
    chars.append(s[len(s)-1])

#Create the word out of single character
join_word = ''.join(chars)

#Get the other words
old_words = [item for item in s.split() if len(item) > 1]

#Form the final string
res = ' '.join(old_words + [join_word])

print(res)

输出看起来像

John plays chess and ludo
