用python通过百度来做的英汉字典

import string
import urllib

key1 = "<img"
key2 = "/>"

pos1 = 0
pos2 = 0

word = raw_input("please input word:")

params = {}
params["word"] = word
params["ssid"] = 0
params["from"] = 0
params["bd_page_type"] = 0
params["tn"] = "wisedict"
params["mark"] = 3
params["uid"] = "frontui_1266379660_6450"
params["vit"] = "qh"

#purl = ""

url = "http://m.baidu.com/s?" 

#for item in params:
#    purl = purl + ("%s=%s&" % (item,str(params[item])))

url = url + urllib.urlencode(params)

#print url

s = urllib.urlopen(url).readlines()[10]

while 1:
    pos1 = 0
    pos2 = 0
    pos1 = s.find(key1,pos2)
    if pos1 < 0:
        break
    else:
        pos2 = s.find(key2,pos1) + len(key2)
        s = s[:pos1] + s[pos2:]

s = s.replace("[]","")
sarr = s.split("<br/>")
for line in sarr:
    print line

整个代码40几行，通过下载m.baidu.com里面的字典的wml文件，进行解析，然后输出。  细节上还不是很完善，不过基本可用了代码的逻辑很简单，先生成地址，然后通过urllib把wml文件下载回来（这个是给手机浏览的）没找到可用的wml解析库，也尝试用xml方式处理，不过效果并不好。但下载回来的wml文件里面关于单词的解释都在第十行这就好办了，接下来处理了一下，最后输出～
