Question

我有一个停用词（德语）列表，我想用来从输入文本中过滤掉相同的词，它看起来像这样：

stopwortlist = ['ab', 'aber','abgesehen', 'alle', 'allein', 'aller', 'alles']
text = input('please put in a Text')
#i have found a way of controlling them online, but it doesnt quite work,
#cause it gives out a list, and all i want is a text (where the words from 
#the list are filtered out

def filterStopwords (eingabeText, stopwords):

    out = [word for word in eingabeText if word not in stopwords]
    return out;

我应该如何修改函数来获取结果？非常感谢提前

Answer 1

将传入的文本拆分为单词（否则您将迭代字符），过滤停用词然后重新加入结果列表。

stopwortlist = ['ab', 'aber','abgesehen', 'alle', 'allein', 'aller', 'alles']
text = 'Some text ab aber with stopwords allein in'

def filterStopwords(eingabeText, stopwords):
    out = [word for word in eingabeText.split() if word not in stopwords]
    return ' '.join(out)

filterStopwords(text, stopwortlist) # => 'Some text with stopwords in'

Answer 2

这里是使用过滤器和连接方法的单线程。

stopwortlist = ['ab', 'aber','abgesehen', 'alle', 'allein', 'aller', 'alles']
text = 'There are ab aber multiple allein abgesehen words in alles this ab list'

print " ".join(filter(lambda x: x not in stopwortlist, text.split()))

#Output
There are multiple words in this list

这基本上使用lambda函数来检查单词是否在stopwortlist中，然后将其从字符串中过滤掉。

在Python中按列表过滤文本
