Converte ImmutableMultiDict with duplicate keys to list of lists or dictionary

Question

So, basically I'm trying to convert an ImmutableMultiDict object to a list of lists or dictionary, but I'm having a hard time trying to figure out how. The thing is I have two values for the same key, so when I try the conversion, I can only get 1 value:

ImmutableMultiDict([('name', 'boom'), ('extension', 'pdf'), ('extension', 'doc')])

When I try dict(object)

{'name': 'boom', 'extension': 'pdf'}

Any suggestion?

What do you want the expected output to be? – James Dec 19 '19 at 22:19 — James, Dec 19 '19 at 22:19

The ImmutableMultiDict object has a lists method. You can use that to convert it to a dictionary with unified keys that have lists for the values.

from werkzeug import ImmutableMultiDict

d = ImmutableMultiDict([('name', 'boom'), ('extension', 'pdf'), ('extension', 'doc')])
dict(d.lists())
# returns:
{'name': ['boom'], 'extension': ['pdf', 'doc']}
