Question

我有一个带有以下文字的txt文件：

water=45 
melon=8 
apple=35 
pineapple=67 
I=43 
to=90 
eat=12 
tastes=100 
sweet=21 
it=80 
watermelon=98 
want=70

我有另一个文件，其中包含以下文字：

I want to eat watermelon
it tastes sweet pineapple

我想输出到：

I want to eat watermelon = 43,70,90,12,98
it tastes sweet pineapple = 80,100,21,67

这是我到目前为止所做的：

import nltk 
f = open(r'C:\folder\dic\file.txt','r')
answer = {}
for line in f:
     k, v = line.strip().split('=')
     answer[k.strip()] = v.strip()

f.close()

print answer.values()

h = open(r'C:\folder\dic\file2.txt','r')
raw=h.read()
tokens = nltk.sent_tokenize(raw)
text = nltk.Text(tokens)


for line in text:
    word = line
    for value in answer.values():
        if value == word:
            word=answer[keys]
        else:
            word="not found"

 print word

在Python中执行此操作的最佳方法是什么？

请检查此代码。

C:\Users\dinesh_pundkar\Desktop>python demo.py
{'apple': '35', 'I': '43', 'sweet': '21', 'it': '80', 'water': '45', 'to': '90',
 'taste': '100', 'watermelon': '98', 'want': '70', 'pineapple': '67', 'melon': '
8', 'eat': '12'}
['I want to eat watermelon', 'it taste sweet pineapple']
I want to eat watermelon  =  43, 70, 90, 12, 98
it taste sweet pineapple  =  80, 100, 21, 67

输出：

height: 100%;
