Here's some info regarding the rp.pyEval(), rp.pyExec(), and rp.pyExecSingle() functions

• You can return variables from python and get them returned to JS, with the only requirement being that they're serializable with json.dumps.
• You can pass an options object as the second argument to the function:
  • stdout: either a string with a css selector to a textarea element or a function that receives a string when the print function is called in python. The default value is console.log.
  • vars: an object that will be available in python as the variable js_vars. Only functions and values that can be serialized with JSON.stringify() will go through.
• JS functions that get passed to python will receive positional args as positional args and kwargs as the this argument
