Python脚本实现文件内容替换

最近因为有一个项目需要从普通的服务器移植到SAE，而SAE的thinkphp文件结构和本地测试的有出入，需要把一些html和js的引用路径改成SAE的形式，为了不手工改，特地速成了一下python的正则表达式和文件操作。主要要求是将某目录下的html和js里面的几个路径变量分别更改成相应的形式，匹配文件名的时候用了正则

import osimport re#all file in the directoryfilelist = []#function to traverse the directorydef recurseDir(path):    for i in os.listdir(path):if os.path.isdir(path + '\\' + i):recurseDir(path + '\\' + i)else:p = path + '\\' + iprint pfilelist.append(p)#replace the file contentdef replace(strFind, strReplace, lines, fileIO):for s in lines:if s.find(strFind) != -1:foutput.write(s)fileIO.write(s.replace(strFind, strReplace))rootpath = os.path.abspath('.')recurseDir(rootpath)pattern1 = re.compile(r'.+html')pattern2 = re.compile(r'.+js')for fileName in filelist:match1 = pattern1.match(fileName)match2 = pattern2.match(fileName)if match1 or match2:lines = open(fileName).readlines()fp = open(fileName + '.temp','w')foutput = open("result.txt", 'w')foutput.write(fileName)if match1:replace('<include file="./Tpl/', '<include file="./App/Tpl/', lines, fp)if match2:replace('xxx/index.php', 'index.php', lines, fp)fp.close()#delete original fileif os.path.exists(fileName):  os.remove(fileName);#rename the temp fileos.rename(fileName + '.temp', fileName)
