python re 与 re.sub替换部分文件

configfileLine = ''
old = ['20003','10003','s3','zxjRYZGI','sid','2018','=5','=19']
new=[clientPort,httpPort,dbName,password,SvrId,openYear,openMonth,openDay]
for old,new  in zip(old,new):
    with open(deploy.servicedir + str(i) + '/Config.lua','r')as f:
        for line in f.readlines():
                 if line.find(str(old)):
                         line = re.sub(str(old),str(new),line)
                         configfileLine += line
                 else:
                         configfileLine += line
    with open(deploy.servicedir + str(i) + '/Config.lua', 'w')as f:
        f.write(configfileLine)
        configfileLine = ''

只修改一个配置文件,configfileLine等于空，读该配置文件覆盖写入，再清空，修改第二项，再重新覆盖写入配置文件

start_stop_Line = ''
for scriptName in ['start.sh','stop.sh']:
        with open(self.servicedir + str(i) + '/bin/' + scriptName, 'r')as f:
                for line in f.readlines():
                        if line.find('1'):
                                line = re.sub('1', str(i), line)
                                start_stop_Line += line
                        else:
                                start_stop_Line += line
        with open(self.servicedir + str(i) + '/bin/' + scriptName, 'w')as f:
                f.write(start_stop_Line)
                start_stop_Line = ''

修改两个配置文件，清宁德start_stop_line写入第一个配置文件，再清空，再写入第二个配置文件
