Calling Python 2 script from Python 3

Question

I have two scripts, the main is in Python 3, and the second one is written in Python 2 (it also uses a Python 2 library).

There is one method in the Python 2 script

Answer 1

You could run python2 from bash using subprocess (python module) doing the following:

From python 3:

#!/usr/bin/env python3
import subprocess

python3_command = "py2file.py arg1 arg2"  # launch your python2 script using bash

process = subprocess.Popen(python3_command.split(), stdout=subprocess.PIPE)
output, error = process.communicate()  # receive output from the python2 script

Where output stores whatever python 2 returned
