Write a function, filter_allowed_words(words, allowed),
which returns a list of words that use only the allowed letters. Example:
>>> filter_allowed_words(['apple', 'banana', 'fig', 'grape'], 'aeplgr')
['apple', 'grape']
Write a function which takes two dictionaries and removes all of their items.
Write a function which takes three strings, it concatenates the first two characters of each string
and returns it.
Example:
>>> concatenate_strings("django", "unchained", "movie")
'djunmo'
Write a function, display_user_books, that takes a user and the borrowed dictionary,
and prints the books borrowed by that user. Example:
>>> borrowed = {'Alice': ['1984']}
>>> display_user_books("Alice", borrowed)
Alice has borrowed:
- 1984
>>> borrowed = {}
>>> display_user_books("Alice", borrowed)
Alice has not borrowed any books.
Write a function that takes no arguments and returns a dictionary with three items, where keys are strings and values are lists.
Write a function, suggest_best_time, that takes a dictionary, members,
and returns the hour when the most members are available.
If there is a tie, return the earliest hour. Example:
>>> members = {'Alice': {9, 10, 14}, 'Bob': {10, 14, 15}, 'Dan': {10, 14}}
>>> suggest_best_time(members)
10
