问题描述
我的代码有一个小问题.我正在尝试反转字符串的单词和字符.例如狗跑"会变成ehT God nar"
代码几乎可以工作.它只是不添加空格.你会怎么做?
def reverseEachWord(str):反向词=""列表=str.split()对于列表中的单词:字=字[::-1]反向词=反向词+词+"返回反向词
解决方案
您走对了.主要问题是 ""
是一个空字符串,而不是一个空格(即使你解决了这个问题,你可能也不希望在最后一个单词后面有一个空格).
以下是您可以更简洁地执行此操作的方法:
>>>s='狗跑了'>>>' '.join(w[::-1] for w in s.split())'ehT God nar'I am having a small problem in my code. I am trying to reverse the words and the character of a string. For example "the dog ran" would become "ehT god nar"
The code almost works. It just does not add spaces. How would you do that?
def reverseEachWord(str):
reverseWord=""
list=str.split()
for word in list:
word=word[::-1]
reverseWord=reverseWord+word+""
return reverseWord
解决方案
You are on the right track. The main issue is that ""
is an empty string, not a space (and even if you fix this, you probably don't want a space after the final word).
Here is how you can do this more concisely:
>>> s='The dog ran'
>>> ' '.join(w[::-1] for w in s.split())
'ehT god nar'
