Path to Blender Python executable

To get the path to the Python interpreter executable file in Blender, we need to check the “bpy.app.binary_path_python” variable.

However, in Blender 2.93 and later, this variable has been removed from the API, and in order to get the desired path to python executable, we need to refer to the “sys.executable”.

The best way for scripting is to define a function that returns the full path to the python executable for any version of Blender:

def python_exec():
    import os
    import bpy
    try:
        # 2.92 and older
        path = bpy.app.binary_path_python
    except AttributeError:
        # 2.93 and later
        import sys
        path = sys.executable
    return os.path.abspath(path)

def python_exec():

import os

import bpy

try:

# 2.92 and older

path = bpy.app.binary_path_python

except AttributeError:

# 2.93 and later

import sys

path = sys.executable

return os.path.abspath(path)

And call it when we need:

print(python_exec())

# C:\Program Files\blender2-93\2.93\python\bin\python.EXE

print(python_exec())

# C:\Program Files\blender2-93\2.93\python\bin\python.EXE
