How to use the python-shell.PythonShell function in python-shell

app.post('/infoContent', function(req, res) {
    // invoke this just once, and send all the data over to the client.
    // This will make the code more responsive.
    // var infoContentParams = req.body;
    var pyShell = new PythonShell('infoContent.py', options)
    // pyShell.send(req.body.data);
    // send the transcript text to the python shell
    pyShell.send(outputtrans.target);
    pyShell.on('message', function(message) {
        infoContentDict = message

        // outputInfoContent.target = infoContentParams.infoContent;
    });
    pyShell.end(function(err) {
