如何操作数组中的字符串？

Question

我试图在一个句子上运行一个先前定义的函数，而且我已经分到了单词串，但是我无法弄清楚如何对它进行循环。请帮忙。代码如下。

def pig_latin_sentence(sentence):
    ''' Converts a string of words separated by spaces to Pig Latin'''
    words=sentence.split(" ")
    for
        pig_latin(word)
        sentence2=sentence2+word
return sentence2

Answer 1

如果pig_latin函数适当地添加空格::

，循环应该看起来像这样

def pig_latin_sentence(sentence):
    ''' Converts a string of words separated by spaces to Pig Latin'''
    words=sentence.split(" ")
    for word in words:
        pig_latin(word)
        sentence2=sentence2+word
return sentence2

但如果没有，那么也许像这样使用join并避免使用map函数的for循环会更好：

def pig_latin_sentence(sentence):
    ''' Converts a string of words separated by spaces to Pig Latin'''
    return ' '.join( map( pig_latin, sentence.split() ) )
