Word未定义

Question

在这个程序中，我试图将索引写入名为“index.txt”的文本文件，并将其打印出来。但是，每当我运行程序时，我都会收到一条错误，说“单词”没有定义，而我的index.txt文件只打印出单词/ tLine数字。

代码：

from string import punctuation

def makeIndex(filename):
    wordIndex = {}
    with open(filename) as f:
        lineNum = 1
        for line in f:
            words = line.lower().split()
            for word in words:
                for char in punctuation:
                    word = word.replace(char, '')
                if word.isalpha():
                    if word in wordIndex.keys():
                        if lineNum not in wordIndex[word]:
                            wordIndex[word].append(lineNum)
                    else:
                        wordIndex[word] = [lineNum]
                lineNum += 1
    return wordIndex

def output(wordIndex):
    print("Word\tLine Numbers")
    for key in sorted(wordIndex.keys()):
        print(key, '\t', end=" ")
        for lineNum in wordIndex[key]:
            print(lineNum, end=" ")
        print()

def main():
    filename = input("What is the file name to be indexed?")
    index = makeIndex(filename)
    output(index)
    with open('index.txt', 'w') as writefile:
        writefile.write("Word/tLine Numbers")
        print('t', end= "")
        for index in range(len(word)):
            print(word[index])
            writefile.write(word[index] + '/n')


main()

输出：
