Lesson 4: count_words

Write a function count_words that takes a file name and
returns a `dict` that stores the tokens as keys and the
number of times a specific token appeared in the file as
values. Remember that a token is a sequence of characters
separated by spaces.

Consider a file `popular_techno_song.txt` with the contents:

```
123456
dun dun dun dun
dun dun dun dun
err
dun dun dun dun dun dun dun dun
dundundundundundundundundundun
er er er er er er ER ER ER ER ER ER der der der der derrr
```

count_words('popular_techno_song.txt') should return the dict

{
    'dun': 16,
    'err': 1,
    'dundundundundundundundundundun': 1,
    'er': 6,
    'ER': 6,
    'der': 4,
    'derrr': 1
}
"""

# Write your function here!


def main():
    print(count_words('popular_techno_song.txt'))


if __name__ == '__main__':
    main()
