old = [‘zxjRYZGI‘,‘20003‘,‘10003‘,‘s3‘,‘= 3‘]

for line in f.readlines():
if line.find(str(old)):
line = re.sub(str(old),str(new),line)
configfileLine += line

configfileLine += line
with open(deploy.servicedir + str(i) + ‘/Config.lua‘, ‘w‘)as f:

configfileLine = ‘‘
with open(passwordPath+‘mongo_pass.txt‘,‘a+‘)as f:
mongoDbname = ‘bz-tw-and-‘ + str(i)
f.write(mongoDbname+‘=‘+password+‘ ‘)
