python - 我有一个 txt 文件。如何获取字典键值并打印它们出现的文本行？

Question

我有一个 txt 文件。我已经编写了代码来查找唯一的单词以及每个单词在该文件中出现的次数。我现在需要弄清楚如何打印这些词出现的行。我该怎么做呢？

Here is a sample output: Analyze what file: itsy_bitsy_spider.txt
Concordance for file itsy_bitsy_spider.txt itsy : Total Count: 2 Line:1: The ITSY Bitsy spider crawled up the water spout Line:4: and the ITSY Bitsy spider went up the spout again

#this function will get just the unique words without the stop words. 
def openFiles(openFile):

    for i in openFile:
        i = i.strip()
        linelist.append(i)
        b = i.lower()
        thislist = b.split()
        for a in thislist:
            if a in stopwords:
                continue
            else:
                wordlist.append(a)
    #print wordlist




#this dictionary is used to count the number of times each stop 
countdict = {}
def countWords(this_list):
    for word in this_list:
        depunct = word.strip(punctuation)
    if depunct in countdict:
        countdict[depunct] += 1
    else:
        countdict[depunct] = 1

from collections import defaultdict

target = 'itsy'
word_summary = defaultdict(list)
with open('itsy.txt', 'r') as f:
    lines = f.readlines()

for idx, line in enumerate(lines):
    words = [w.strip().lower() for w in line.split()]
    for word in words:
        word_summary[word].append(idx)

unique_words = len(word_summary.keys()) 
target_occurence = len(word_summary[target]) 
line_nums = set(word_summary[target])

print "There are %s unique words." % unique_words 
print "There are %s occurences of '%s'" % (target_occurence, target) 
print "'%s' is found on lines %s" % (target, ', '.join([str(i+1) for i in line_nums]))
