I am creating a loop in order to append continuously values from user input to a dictionary but i am getting this error:
AttributeError: 'dict' object has no attribute 'append'
This is my code so far:
for index, elem in enumerate(main_feeds):
print(index,":",elem)
temp_list = index,":",elem
li = {}
print_user_areas(li)
while True:
n = (input('\nGive number: '))
if n == "":
break
else:
if n.isdigit():
n=int(n)
print('\n')
print (main_feeds[n])
temp = main_feeds[n]
for item in user:
user['areas'].append[temp]
Any ideas?

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
As the error suggests, append is not a method or attribute, meaning you cannot call append in the dictionary user.
Instead of
user['areas'].append[temp]
Use
user['areas'].update[temp]
Either use dict.setdefault() if the key is not added yet to dictionary :
dict.setdefault(key,[]).append(value)
or use, if you already have the keys set up:
dict[key].append(value)
