python3 traceback error
Altering the default Python interpreter in a Ubuntu derived distribution is a Bad Idea. Very many system utilities expect python
to resolve to the expected version and get very unhappy when it doesn't.
Better would be (obviously shell dependent):
export PATH="${HOME}/bin:${PATH}"
ln -s /usr/bin/python2.7 $HOME/bin/python
making it your default interpreter but leaving the system utilities as they expect.

My first guess as to why this didn't work is that you didn't completely clean up the changes you made.
sudo rm /usr/local/bin/python
sudo apt-get install --reinstall python
Should clear up the changes you reported here and restore the distribution default Python interpreter to be the system-wide default.
Then, remove your user alias that I suggested you make above:
rm $HOME/bin/python
And check if you still get the Python traceback when a shell command is not found. If you still get the traceback, I can't think of a standard mechanism that would cause that to happen. Therefore you'll need to give us more information about what shell you are using (presumably bash) and add the output of the commands
complete | grep python
alias | grep python
python -V
to your question.

Whenever I mistype any command in terminal instead of getting
Error:Command not found
I get this python message errorTraceback (most recent call last): File "/usr/lib/python3.3/site.py", line 631, in <module> main() File "/usr/lib/python3.3/site.py", line 616, in main known_paths = addusersitepackages(known_paths) File "/usr/lib/python3.3/site.py", line 284, in addusersitepackages user_site = getusersitepackages() File "/usr/lib/python3.3/site.py", line 260, in getusersitepackages user_base = getuserbase() # this will also set USER_BASE File "/usr/lib/python3.3/site.py", line 250, in getuserbase USER_BASE = get_config_var('userbase') File "/usr/lib/python3.3/sysconfig.py", line 580, in get_config_var return get_config_vars().get(name) File "/usr/lib/python3.3/sysconfig.py", line 530, in get_config_vars _init_posix(_CONFIG_VARS) File "/usr/lib/python3.3/sysconfig.py", line 403, in _init_posix from _sysconfigdata import build_time_vars File "/usr/lib/python3.3/_sysconfigdata.py", line 6, in <module> from _sysconfigdata_m import * ImportError: No module named '_sysconfigdata_m'
I know that after installing python3.x and trying to make it my default interpreter this error has gone this way.
$ lsb_release -rd Description: Linux Mint 14 Nadia Release: 14
/usr/lib/command-not-found
is working well also.
Can I get back to my default python version ? simply I didsudo ln -sf /usr/bin/python2.7 /usr/local/bin/python
is it enough to get 2.7 as default interpreter ?
Any idea how to get rid off this hell message error ?-
