Convert Javascript array to python list?

python

Solution

JavaScript part - encoding

In Javascript you do:

var arr = ["a","b",,,"e"];
var json_string = JSON.stringify(arr);

then you somehow pass `json_string` (now equal to "`["a","b",null,null,"e"]`" string) from JavaScript to Python.

Python part - decoding

Then, on Python side do:

json_string = '["a","b",null,null,"e"]'  # passed from JavaScript

try:
    import simplejson as json
except (ImportError,):
    import json

result = json.loads(json_string)

As a result you get `[u'a', u'b', None, None, u'e']` in Python.

Dependencies

The above solutions require:

- `JSON.stringify()` in JavaScript, which is in all mobile browsers, Chrome, Firefox, Opera, Safari and in IE since version 8.0 (more detailed list of compatible browsers is here),

- `json` Python library (the above code will use `simplejson` optionally, if available, but is not required), which comes in standard library,

So, in short there are no external dependencies.
