将PHP函数转换为Python 3

尝试将PHP函数转换为Python，我是Python方面的新手，这就是我所尝试的

Python->

def stopWords(text, stopwords):
  stopwords = map(to_lower(x),stopwords)
  pattern = '/[0-9\W]/'
  text = re.sub(pattern, ',', text)
  text_array = text.partition(',');
  text_array = map(to_lower(x), text_array);
  keywords = []
for term in text_array:
  if(term in stopwords):
     keywords.append(term)
 return filter(None, keywords)

stopwords = open('stop_words.txt','r').read()
text = "All words in the English language can be classified as one of the eight different parts of speech."
print(stopWords(text, stopwords))

PHP->

function stopWords($text, $stopwords)
    {

    // Remove line breaks and spaces from stopwords

    $stopwords = array_map(
    function ($x)
        {
        return trim(strtolower($x));
        }

    , $stopwords);

    // Replace all non-word chars with comma

    $pattern = '/[0-9\W]/';
    $text = preg_replace($pattern, ',', $text);

    // Create an array from $text

    $text_array = explode(",", $text);

    // remove whitespace and lowercase words in $text

    $text_array = array_map(
    function ($x)
        {
        return trim(strtolower($x));
        }

    , $text_array);
    foreach($text_array as $term)
        {
        if (!in_array($term, $stopwords))
            {
            $keywords[] = $term;
            }
        };
    return array_filter($keywords);
    }

$stopwords = file('stop_words.txt');


$stopwords = file('stop_words.txt');
$text = "All words in the English language can be classified as one of the eight different parts of speech.";
print_r(stopWords($text, $stopwords));

我在cmd上看到python中的错误： 缩进错误：未缩进与任何外部缩进级别不匹配

请找出我做错了什么，python中的“文件”选项

应该缩进的

，当您编写它时，它似乎超出了函数的范围。此外，最后一个返回值不与for或函数对齐

正确的缩进应如下所示：

def stopWords(text, stopwords):
  stopwords = map(to_lower(x),stopwords)
  pattern = '/[0-9\W]/'
  text = re.sub(pattern, ',', text)
  text_array = text.partition(',');
  text_array = map(to_lower(x), text_array);
  keywords = []
  for term in text_array:
    if(term in stopwords):
      keywords.append(term)
  return filter(None, keywords)

您没有正确指定代码行的用途。与PHP不同，缩进在Python中非常重要。您知道为什么需要在Python中使用缩进吗？您知道文本数组中术语的
行：
结束了函数吗？@Matthias不，我不知道，但我有兴趣知道that@Matthias好的，明白了，Python中的空格数（enter）是定义属于一起的事物的方法。在PHP中使用
{
和
}
，代码的缩进是可选的。在Python中，代码的缩进定义了代码结构。@LovePreetighBatth只要正确缩进函数，它就应该工作
