如何从node.js的python-shell中的python代码获取返回值？

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')

Answer 1

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())')
