将文件读入python列表中。 如何拿出单词

Question

I am reading a file into a list and spliting it so that every word is in a list. However I do not want specific words to be brought up in the list, I would like to skip them. I called the trash list filterList written below.

this is my code:

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

I am getting this error:

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

Can someone help ? thanks

You need to give,

aList.append(word)

List object only has the attribute append . And also you need to declare the list first. Then only you could append the items to that list.

ie,

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)
