Write a Python script that takes a Scrabble rack as a command-line argument and prints all valid Scrabble words that can be constructed from that rack, along with their Scrabble scores, sorted by score. An example invocation and output:

====Step 2: get the rack====
Write the code to get the Scrabble rack (the letters available to make words) from the command line argument passed to your script. For example if your script were called `scrabble_cheater.py`, if you ran
Handle the case where a user forgets to supply a rack; in this case, print an error message saying they need to supply some letters

</ul>
====Step 3: find valid words====
Write the code to find all words from the word list that are made of letters that are a subset of the rack letters. There are many ways to do this, but here's one way that is easy to reason about and is fast enough for our purposes: go through every word in the word list, and for every letter in that word, see if that letter is contained in the rack. If it is, save the word in a <tt>valid_words</tt> list. Make sure you handle repeat letters: once a letter from the rack has been used, it can't be used again.
