多くのユニークな単語リストへ

Question

先週の宿題プロジェクトです。私は問題があったので、それを回しませんでした。しかし、私は戻って、私はそれらを働かせることができるかどうかを確認したい。これで、正しい単語をアルファベット順に印刷しました。私は、3つの別個のリストを、リスト中の単語の数が異なるすべてのものを印刷しているという問題があります。これをどうすれば解決できますか？以下は

import string 
def process_line(line_str,word_set): 
    line_str=line_str.strip() 
    list_of_words=line_str.split() 
for word in list_of_words: 
    if word!="--": 
     word=word.strip() 
     word=word.strip(string.punctuation) 
     word=word.lower() 
     word_set.add(word) 
def pretty_print(word_set): 
    list_of_words=[] 
    for w in word_set: 
     list_of_words.append(w) 
     list_of_words.sort() 
    for w in list_of_words: 
     print(w,end=" ") 
word_set=set([]) 
fObject=open("gettysburg.txt") 
for line_str in fObject: 
    process_line(line_str,word_set) 
    print("\nlength of the word set: ",len(word_set)) 
    print("\nUnique words in set: ") 
    pretty_print(word_set) 

私が得る出力され、私はそれは私に138個の単語との最後の1を与えたいです。助けをお待ちしています。
