To exit from Python interactive you can type CTRL + D. You can also type exit() or quit() to exit.

To check python location you can use command below

/usr/bin/python

When we checked /usr/bin/python, it’s actually a symbolic link to /usr/bin/python2.7.


$ <span class="token function">ls</span> -l /usr/bin/python
lrwxrwxrwx 1 root root 9 Nov 24  2017 /usr/bin/python -<span class="token operator">></span> python2.7
