My python version 2.7 i installed just before few minutes but its continuously taking pythin2.6 library. I havn't more knowledge about python.

Help me..!! Thanks in advance ...!!

Your problem is that the default python version is 2.6, and it is running twistd for that version.

Run the program from the site-packages of Python 2.7: use usr/lib/python2.7/site_package/twistd instead of twistd. To make it more convenient for yourself, you can set an alias for twistd with Python 2.7 (twistd_27) to point to the right version as follows:

alias twistd_27='<path to twistd>'
