python学习日记-百度翻译GUI

跟女朋友聊天的时候，女朋友抱怨每次翻译都要打开百度网页上找，这让我有了做一个小的翻译界面的想法，搜索百度翻译居然发现其有API，正合我意，上百度翻译开放平台注册一个个人测试帐号就可以了，东拼西凑，做出了来一个小程序，代码如下：

 1 # coding=utf-8
 2 from Tkinter import *
 3 import tkMessageBox
 4 import urllib2
 5 import hashlib
 6 import json
 7
 8
 9 trans_id = ‘*****************‘    #提供百度翻译的APP ID
10 trans_password = ‘***********‘    #提供密钥
11 phone_num = ‘************‘    #要求是salt，其实电话号码就行
12
13
14 def count(word):
15     c = 0
16     for i in word:
17         c += 1
18     return c
19
20
21 def md5hex(word):
22     if isinstance(word, unicode):
23         word = word.encode("utf-8")
24     elif not isinstance(word, str):
25         word = str(word)
26     m = hashlib.md5()
27     m.update(word)
28     return m.hexdigest()
29
30
31 def trans(word, fr=‘en‘, to=‘zh‘):
32     word_num = count(word)
33     sign = md5hex(trans_id + word + phone_num + trans_password)
34     api = ‘http://api.fanyi.baidu.com/api/trans/vip/translate?q=‘ + word + ‘&from=‘ + ‘en‘ + ‘&to=‘ + ‘zh‘ + ‘&appid=20161120000032369&salt=‘ + phone_num + ‘&sign=‘ + sign
35     trans_data = urllib2.urlopen(api).read()
36     trans_data = json.loads(trans_data)
37     trans_data = trans_data[‘trans_result‘][0][‘dst‘]
38     return trans_data
39
40
41 class Application(Frame):
42     def __init__(self, master=None):
43         Frame.__init__(self, master, bd=30)
44         self.pack()
45         self.createWidgets()
46
47     def createWidgets(self):
48         self.nameInput = Entry(self)
49         self.nameInput.pack()
50         self.alertButton = Button(self, text=‘翻译‘, command=self.hello)
51         self.alertButton.pack()
52
53     def hello(self):
54         name = self.nameInput.get()
55         result = trans(name)
56         tkMessageBox.showinfo(‘翻译结果‘, ‘Result: %s‘ % result)
57
58 app = Application()
59 # 设置窗口标题:
60 app.master.title(‘Translate‘)
61 # 主消息循环:
62 app.mainloop()

测试运行结果还行，截图如下：
