python - 将文件读入python列表中。如何拿出单词

我正在将文件读入列表并将其拆分，以便每个单词都在列表中。但是，我不想在列表中显示特定的单词，我想跳过它们。我称下面的垃圾列表filterList。

这是我的代码：

with open('USConstitution.txt') as f:
    lines = f.read().split()              #read everything into the list

filterList = ["a","an","the","as","if","and","not"]  #define a filterList

for word in lines:
    if word.lower() not in filterList:
        word.append(aList)   #place them in a new list called aList that does not contain anything in filterList


print(aList)    #print that new list

我收到此错误：

AttributeError: 'str' object has no attribute 'append'

有人可以帮忙吗？谢谢

最佳答案

你需要付出

aList.append(word)

列表对象仅具有属性append。而且您还需要先声明列表。然后，只有您可以将项目追加到该列表中。

即

with open('USConstitution.txt') as f:
    lines = f.read().split()              #read everything into the list

filterList = ["a","an","the","as","if","and","not"]  #define a filterList
aList = []
for word in lines:
    if word.lower() not in filterList:
        aList.append(word)   #place them in a new list called aList that does not contain anything in filterList


print(aList)
