Python2 vs Python3

See original GitHub issue

Hi @PiotrDabkowski ,

The following works in python2… however we get an error when using python3

  File "/usr/local/lib/python3.5/dist-packages/js2py/base.py", line 547, in to_primitive
    return self.default_value(hint)
  File "/usr/local/lib/python3.5/dist-packages/js2py/base.py", line 455, in default_value
    'Cannot convert object to primitive value')
js2py.internals.simplex.JsException: TypeError: Cannot convert object to primitive value

test code is as follows…

import js2py
import base64

def atob(s):
   return base64.b64decode('{}'.format(s))

context = js2py.EvalJs({ "atob": atob })
context.eval(

Ah, okay

import js2py
import base64

def atob(s):
   return base64.b64decode('{}'.format(s)).decode('utf-8')

context = js2py.EvalJs({ "atob": atob });

The reason is your atob function that returns the bytes instead of string. The bytes are converted to PyJsObjectWrapper which cannot be converted to a primitive value, hence the error 😃

I guess it should be converted to native Js type just like string and unicode types, but this is done currently.
