从字典

Question

转换价值，关键我有以下内容的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 

和我有以下文本另一个文件：

I want to eat watermelon 
it tastes sweet pineapple 

我要输出到：

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

这是我到目前为止有：

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中这样做的最好方法是什么？

请检查这个代码。

import re 
f = open(r'C:\Users\dinesh_pundkar\Desktop\val.txt','r') 
val_dict = {} 
for line in f: 
    k, v = line.strip().split('=') 
    val_dict[k.strip()] = v.strip() 
f.close() 

print val_dict 

h = open(r'C:\Users\dinesh_pundkar\Desktop\str_txt.txt','r') 
str_list = [] 
for line in h: 
    str_list.append(str(line).strip()) 

print str_list 

tmp_str = '' 
for val in str_list: 
    tmp_str = val 
    for k in val_dict.keys(): 
      if k in val: 
       replace_str = str(val_dict[k]).strip() + "," 
       tmp_str= re.sub(r'\b{0}\b'.format(k),replace_str,tmp_str,flags=re.IGNORECASE) 

    tmp_str = tmp_str.strip(",") 
    print val, " = ", tmp_str 
    tmp_str = '' 

输出：

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
