@user2357112 I think he means the order of __first occurrence__ of the words. — Shiva, Jun 29 '17 at 02:25

You can't really have an order in a dictionary. Look at the OrderedDict module to print things in the order you store them

import collections 
s = input("")
slist = s.split()
finaldict = collections.OrderedDict()
for word in slist:
    if not finaldict.get(word):
        finaldict[word] = slist.count(word)

for palabra in finaldict:
    finaldict[palabra]=str(finaldict[palabra])
    print(palabra,finaldict[palabra])

Dictionaries by their nature are unordered. You want to use an OrderedDict (found in the collections module). You would assign to an OrderedDict in the same way you would a regular dict, and initialize it by passing a list of 2-tuples to the OrderedDict constructor. For example:

>>> from collections import OrderedDict
>>> spam = OrderedDict([('a', 1), ('b', 2)])
>>> spam['c'] = 3
>>> print spam
OrderedDict([('a', 1), ('b', 2), ('c', 3)])
>>> eggs = OrderedDict()
>>> eggs['a'] = 1
>>> print eggs
OrderedDict([('a', 1)])
