初学Python时需要注意相关事项,首先初学Python时要先知道什么是Python?那么下面说一下什么是Python,所谓Python:是一种面向对象、直译式计算机程序设计语言,也是一种功能强大而完善的通用型语言。
我们目前要把一个表态HTML页面转换成PORTAL。由于表态页面数量很大,所以我们采用动态改写的方法。由于这篇的目的不是介绍我们的项目。所以直接说我的脚本。由于我们的工作,我们现在做操作前要对所以的静态页面进行简单的标记分析。这里主要分析TABLE,TR和TD。
下面贴下我的代码:初学Python主要是两个文件:
- import os, fnmatch
- # judge comment tag to delete comment statement
- def judgeComment (line):
- openTag = line.find('<!--')
- closeTag = line.find('-->')
- if openTag != -1:
- if closeTag != -1:# <!-- -->
- return 1
- else:#<!--
- return 2
- elif closeTag != -1:#-->
- return 3
- else:#
- return 4
- # sort for a 2 dimension list(array)
- def sortFor2di (listtosort):
- size = len(listtosort)
- for i in range(size-1):
- for j in range(i + 1,size):
- list1 = listtosort[i]
- list2 = listtosort[j]
- if list1[0] > list2[0]:
- listtosort[i],listtosort[j] = listtosort[j],listtosort[i]
- # get all tags in a line in the form of list
- def getLineTagList (line):
- taglist = []
- addTag2List (line,'table',taglist)
- addTag2List (line,'tr',taglist)
- addTag2List (line,'td',taglist)
- sortFor2di (taglist)
- return taglist
- def addTag2List (line,tag,taglist):
- pos = line.find('<'+tag)
- if pos != -1:
- taglist.append([pos,'<'+ tag + '>'])
- pos = line.find('</'+tag+'>')
- if pos != -1:
- taglist.append([pos,'</' + tag + '>'])
- def addDelTag(itemlist,stackList):
- tag = itemlist[1]
- res = 0
- res += judgeWhichTag (tag,'table',stackList)
- res += judgeWhichTag (tag,'tr',stackList)
- res += judgeWhichTag (tag,'td',stackList)
- if res != 0:
- return -1
- else:
- return 1
- #
- def judgeWhichTag (tag,lable,stackList):
- if tag == '<' + lable + '>':
- stackList.append(lable)
- return 0
- elif tag == '</' + lable + '>':
- size = len(stackList)
- if size < 1:
- return -1
- elif stackList[size - 1] == lable:
- del(stackList[size -1 ])
- return 0
- else:
- return -1
- else:
- return 0
- # used to deal tag
- def tagDeal (tag, line,stackList):
- openTag = line.find('<'+tag)
- closeTag = line.find('</'+tag+'>')
- if openTag != -1:
- stackList.append (tag)
- if closeTag == -1:
- return 1
- if closeTag != -1:
- size = len(stackList)
- if size < 1:
- return -1
- else:
- lastItem = stackList[size - 1]
- if lastItem != tag:
- return -1
- else:
- del (stackList[size - 1])
- return 1
- def find (pattern,startdir=os.curdir):
- files = []
- os.path.walk(startdir,visitor,(pattern,files))
- files.sort()
- return files
- def visitor ((pattern,files),thisdir,names):
- for name in names:
- if fnmatch.fnmatch(name,pattern):
- fullpath = os.path.join(thisdir,name)
- files.append(fullpath)
申明一下,我是初学Python。上面的程序写得很乱,以后有时间再修改或加点注释。当然很欢迎各位朋友给点意见。不过,***的结果是我们的总共1000表态页面中共有200个页面这三种标签有错误。这就意味着有一大堆事情要处理。至于怎么做我们还没做好决定。
