I know in php I could just use $_GET['key1']['key2'] to retrieve GET data that is sent in the form of an array but is that something possible in Python as I just receive a string and it's not recognized as an array/list.

I use flask/werkzeug if that matters.

request.args is a MultiDict instance (MultiDict, Flask request api).

request.args[key] ## returns a single value, the first if there are multiple
request.args.getlist(key) ## returns a list

If you want to submit structures more complex than can be encoded using simple key:vals, consider sending a json encoded object.

Also, look at the jQuery recursive param serialisation pattern, and the jquery-unparam lib which can deserialise it.
