Accessing dictionary value by index in python [duplicate]

Question

I would like to get the value by key index from a Python dictionary. Is there a way to get it something like this?

dic = {} value_at_index = dic.ElementAt(index) 

where index is an integer

Answer 1

In Python versions before 3.7 dictionaries were inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = list(dic.values())[index] 

Bear in mind that prior to Python 3.7 adding or removing an element can potentially change the index of every other element.

Answer 2

Let us take an example of dictionary:

numbers = {'first':0, 'second':1, 'third':3} 

When I did

numbers.values()[index] 

I got an error:'dict_values' object does not support indexing

When I did

numbers.itervalues() 

to iterate and extract the values it is also giving an error:'dict' object has no attribute 'iteritems'

Hence I came up with new way of accessing dictionary elements by index just by converting them to tuples.

tuple(numbers.items())[key_index][value_index] 

for example:

tuple(numbers.items())[0][0] gives 'first' 

if u want to edit the values or sort the values the tuple object does not allow the item assignment. In this case you can use

list(list(numbers.items())[index])
