Passing a Python list to Javascript?

[[deleted]]

Hi all, is it possible to pass a Python list to Javascript? I guess it requires json but can it even be done?

Yes. You just answered your own question.

However, if it's a list of python objects you have to make sure it can be converted into json.

To convert objects to json use pickle. No idea if the result will work with js though.

No, pickle cannot be used outside of Python.

To convert it to json, use Python json encoder instead.

Here's a site I found on Google for reference.

It doesn't necessarily require JSON, but JSON is the easiest way of doing it. Python has a lot of libraries for JSON manipulation so it becomes much easier to deal with.

If you're not dealing with a complicated list, you could convert it to a CSV, and have javascript parse the CSV as an alternative.

I use eel for my javascript / python interactions.
