Ask the user to enter a word. Produce all anagrams of that word. If the word contains multiple copies of a letter, it is acceptable if you produce certain anagrams multiple times. For example, if the word is "ape", you produce "aep", "ape", "eap", "epa", "pae", and "pea" (in any order).

Assignment

Write a generator function anagrams that takes one argument word (str). The generator must yield all anagrams of word, as str values. The order in which the anagrams are yielded does not matter, and if word contains a letter more than once, some anagrams may be yielded more than once; there is no need to filter out these duplicates.

Example

>>> sorted(anagrams('ape'))
['aep', 'ape', 'eap', 'epa', 'pae', 'pea']

>>> sorted(set(anagrams('eve')))
['eev', 'eve', 'vee']
