Question

How do I find the full path of the currently running Python interpreter from within the currently executing Python script?

---

_{See How do I check which version of Python is running my script? if you are specifically interested in the version of Python for the currently running interpreter – for example, to bail out with an error message if your script doesn’t support that Python version, or conditionally disable certain modules or code paths.}

Answer 1

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

import sys

print(sys.executable)

which is now documented here
