I know this is not what you asked, but why not convert to a
configuration file that can be processed by ConfigParser?

[service_A]
dir=C:\test
username=test
password=test

Then you can do the following to change:

import ConfigParser
INI=ConfigParser.ConfigParser()
INI.read(r'C:\program.ini')
INI.set('service_A','username','newusername')
fp=open(r'c:\program.ini','w')
INI.write(fp)
fp.close()
