Your mission

Implement tally_words, which returns how many times each word of text appears.

See it in action

tally_words("pong ping ping")

{'pong': 1, 'ping': 2}

tally_words("row row Row\nboat")

{'row': 2, 'Row': 1, 'boat': 1}

tally_words(" ")

{}

Your checklist

• text is any string whose only whitespace characters are spaces, tabs and newlines. A word is a run of characters that contains none of them; any amount of them separates two words.
• Words are compared exactly: "Row", "row" and "row!" are three different words.
• Return a dict that maps each different word of text to the number of times it appears.
• The keys come in the order in which each word first appears in text.
• A text that contains no word gives {}.
