How to get return value from python codes in python-shell of node.js?

Question

I want to get return value of tmp.py in tmp.js. How can I solve this?

def function():
    return 'tmp'

const {PythonShell} = require('python-shell');
PythonShell.run('tmp.py')

A file does not have a return value. A function does. Modifiy your tmp.py such that it includes the call to the function: if __name__ == '__main__': function() — WiseDev

A file does not have a 'return' value. A function however, does.

Either:

modify your tmp.py such that the desired function gets called

def function()
    return 'tmp'

if __name__ == '__main__':
    var = function()
    print(var)

or directly run the code in the shell

 const {PythonShell} = require('python-shell');
 PythonShell.run('import tmp')
 PythonShell.run('print(tmp.function())')
