A string is an anagram of another string if they both have the same
characters, but they do not appear in exactly the same order. Define a function
anagrams(string1,string2) that takes two strings and returns True if they are anagrams,
and False otherwise. You can use the in and not in operators to do this problem
>>>anagrams("cat","cata")
False
>>>anagrams("cat","cat")
False
>>>anagrams("cat","aat")
False
>>>anagrams("cat","act")
True
>>>anagrams("staple","plates")
True
>>>anagrams("leap","pale")
True
