Hints

counts.get(w, 0) + 1 increases a count, starting from 0.

Dictionaries remember insertion order.

Since Python 3.7 dicts keep insertion order, so iterating gives first-appearance order.

Show solution

counts = {}
for w in input().split():
    counts[w] = counts.get(w, 0) + 1
for w, c in counts.items():
    print(w, c)
