Sending lists with the Python lib requests

Question

I have a python dict containing a list, for example:

d = {"x": 1, "y": ["a", "b", "c"]}

I want to send this dict with a POST from my python project using the requests lib like this:

requests.post(url, d, verify=False)

I manage to send and recieve the request fine but the problem is that when I'm printing the request.POST dict in my Django view it looks like this:

{"y": "c", "x": "1"}

The y key containing the list doesn't look as expected as the list has been reduced to just the last object of the list, in this case "c". How do I send the list properly?

I meant to say list, changed all arrays in my question.

You need to use the QueryDict.getlist() method to retrieve all values for a parameter that is repeated in the request:

y = request.POST.getlist('y')

This assumes that you instead posted d = [('x', 1), ('y', 'a'), ('y', 'b'), ('y', 'c')]; nested lists are not supported by requests.

Right, thanks, I do use the getlist method but are confusing myself by printing the whole request.POST. The y actually contains an array and not just the "c".
