Support for translating Jquery?

[anshulthakur]

Hi, I was hoping to use Js2Py to translate a JS module to Python. However, the module itself depends on Jquery. So, I tried translating the Jquery js to python first. The conversion of code from JS to python works fine for both the modules.

However, on importing the jquery module, Js2Py throws an exception which I cannot work around.

Here's what I did:

js2py.translate_file('jquery-3.3.1.min.js', 'jquery.py')
from jquery import jquery

Here's the exception:
