Stuck? The idea behind dictionaries

A dictionary links keys to values, like words to meanings: ages["Ann"] = 12. Looking up a key is fast, however big it is.

.get(key, 0) gives a default when the key isn't there; looping over a dictionary gives its keys, .items() gives keys and values together.

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

Watch for: Reading a key that isn't there stops the program with a KeyError: check with in, or use .get().
