I want to run a Python script from a Python script with subprocess, and I wish to do it using the same interpreter for each of them.
I'm using virtualenv, so I'd like to do something like:
subprocess.Popen('%s script.py' % python_bin)
How do I get python_bin?
It should be /usr/bin/python outside a virtualenv, and /path/to/env/bin/python in a virtualenv.

1 Answer. For finding the full path of the Python interpreter you can use sys. executable which contains the full path of the currently running Python interpreter.
To select a specific environment, use the Python: Select Interpreter command from the Command Palette (Ctrl+Shift+P). Note: If the Python extension doesn't find an interpreter, it issues a warning.
On Windows, this depends on where we installed Python; the default directory is c:\Python32. If we run the Python Shell from the command line, the current working directory starts as the directory we were in when we ran python3.
The name of the interpreter is stored in the variable sys.executable

I found it by:
>>> import sys
>>> help(sys)
