How to correctly sort dictionary by its value in Python?

Question

Given the dictionary below, I tried to sort it by the value order 0,1,2,3,4 without any success

items = {
            'Customer'          : ['Form', 'Customer is module for recording information.', 0], 
            'Age'               : ['Label', 'This field for input Age of Customer automatically calculated by system against date of birth.', 4], 
            'Salutation'        : ['Label', 'A greeting in words or actions or the words used at the beginning of a letter or speech.', 2], 
            'As a Guarantor'    : ['Label', 'Whether or not a customer is a guarantor to another customer.', 1], 
            'First Name English': ['Label', 'The name that was given to you when you were born and that comes before your family name.', 3]
        }

print "before sort dictionary"
print items

items    = dict(sorted(items.items(),key=lambda (k,v):int(v[2]))) # Sort Dictionary By key/value 'Order'
print "after sort dictionary"
print items

After sorted(), the dictionary slightly changed but still not correctly, the item after sorted is as this:

{
    'Customer'          : ['Form', 'Customer is module for recording information.', 0], 
    'As a Guarantor'    : ['Label', 'Whether or not a customer is a guarantor to another customer.', 1], 
    'Age'               : ['Label', 'This field for input Age of Customer automatically calculated by system against date of birth.', 4], 
    'Salutation'        : ['Label', 'A greeting in words or actions or the words used at the beginning of a letter or speech.', 2], 
    'First Name English': ['Label', 'The name that was given to you when you were born and that comes before your family name.', 3]
}

Please kindly help how can sort this dictionary correctly? Thanks

default `dict` is not ordered in python. Maybe you can look at `orderedDict`. — Sociopath, Mar 23 '19 at 07:23
Use python 3.7 where dicts are insertion ordered by default or use `orderedDict` — Jibin Mathews, Mar 23 '19 at 07:25
@AkshayNevrekar, Thanks, I know about that fact, and googled around and found something of sorted() method that worthwhile to try. Without knowing why, some value it sorted correctly, but some are not, like this one. — Houy Narun, Mar 23 '19 at 07:27
Huh? If you know that dicts aren't ordered, then what's your question? — Aran-Fey, Mar 23 '19 at 07:28
@Aran-Fey somehow my application needs that, to sort the value of `dict` and I know there must be workaround solution. Thanks — Houy Narun, Mar 23 '19 at 07:31
Use [`collections.OrderedDict`](https://docs.python.org/3/library/collections.html#collections.OrderedDict). — Aran-Fey, Mar 23 '19 at 07:32
