Append a dictionary to a dictionary no overide-CodePudding

dic1 ={'materials_id': 5, 'name': 'paint', 'capacity': 3}
dic2 ={'materials_id': 4, 'name': 'chemistry', 'capacity': 3}

become:

data ={ {'materials_id': 5, 'name': 'paint', 'capacity': 3}, {'materials_id': 4, 'name': 'chemistry', 'capacity': 3}}

You can't hash a dictionary, so creating a set of dictionaries is not possible.

Try creating a tuple or list instead:

>>> dic1 = {'materials_id': 5, 'name': 'paint', 'capacity': 3}
>>> dic2 = {'materials_id': 4, 'name': 'chemistry', 'capacity': 3}
>>> data = (dic1, dic2)
>>> data
({'materials_id': 5, 'name': 'paint', 'capacity': 3}, {'materials_id': 4, 'name': 'chemistry', 'capacity': 3})
>>> data = [dic1, dic2]
>>> data
[{'materials_id': 5, 'name': 'paint', 'capacity': 3}, {'materials_id': 4, 'name': 'chemistry', 'capacity': 3}]

Alternatively, you could utilize immutabledict:

>>> from immutabledict import immutabledict
>>> data = {immutabledict(dic1), immutabledict(dic2)}
>>> data
{immutabledict({'materials_id': 4, 'name': 'chemistry', 'capacity': 3}), immutabledict({'materials_id': 5, 'name': 'paint', 'capacity': 3})}

Maybe a different way to write that could be:

Data = { 'materials_id': id_indexlist[0] , 'name' : names_list[0], ...

Instead using a dictionary inside another dictionary you could combine a dictionary with several lists.
