Like the error message suggests, dictionaries in Python do not provide an append operation.
You can instead just assign new values to their respective keys in a dictionary.
mydict = {}
mydict['item'] = input_value
If you’re wanting to append values as they’re entered you could instead use a list.
mylist = [] mylist.append(input_value)
Your line user['areas'].append[temp] looks like it is attempting to access a dictionary at the value of key 'areas', if you instead use a list you should be able to perform an append operation.
Using a list instead:
user['areas'] = []
On that note, you might want to check out the possibility of using a defaultdict(list) for your problem. See here
