Find full path of the Python interpreter?

sys.executable contains full path of the currently running Python interpreter.

import sysprint(sys.executable)

which is now documented here

Just noting a different way of questionable usefulness, using os.environ:

import ospython_executable_path = os.environ['_']


$ python -c "import os; print(os.environ['_'])"/usr/bin/python

There are a few alternate ways to figure out the currently used python in Linux is:

  1. which python command.
  2. command -v python command
  3. type python command

Similarly On Windows with Cygwin will also result the same.

kuvivek@HOSTNAME ~$ which python/usr/bin/pythonkuvivek@HOSTNAME ~$ whereis pythonpython: /usr/bin/python /usr/bin/python3.4 /usr/lib/python2.7 /usr/lib/python3.4        /usr/include/python2.7 /usr/include/python3.4m /usr/share/man/man1/python.1.gzkuvivek@HOSTNAME ~$ which python3/usr/bin/python3kuvivek@HOSTNAME ~$ command -v python/usr/bin/pythonkuvivek@HOSTNAME ~$ type pythonpython is hashed (/usr/bin/python)

If you are already in the python shell. Try anyone of these.Note: This is an alternate way. Not the best pythonic way.

>>> import os>>> os.popen('which python').read()'/usr/bin/python\n'>>>>>> os.popen('type python').read()'python is /usr/bin/python\n'>>>>>> os.popen('command -v python').read()'/usr/bin/python\n'>>>>>>

If you are not sure of the actual path of the python command and is available in your system, Use the following command.

pi@osboxes:~ $ which python/usr/bin/pythonpi@osboxes:~ $ readlink -f $(which python)/usr/bin/python2.7pi@osboxes:~ $ pi@osboxes:~ $ which python3/usr/bin/python3pi@osboxes:~ $ pi@osboxes:~ $ readlink -f $(which python3)/usr/bin/python3.7pi@osboxes:~ $
