Homework: Write a function to score a scrabble word.
values is a global dict formatted as values = {'a': 1, 'b': 3,...}
The docstring is supplied as part of the course, thus I'm only looking for feedback on the actual program logic.
I could have written a bunch of variables, iterated over the string word, looking up points from values, etc., but I've been reading about functional programming lately and this is my first attempt at something "non-procedural".
I feel like this code (while working) looks terrible, isn't easily understood, and has more than one code smell. For example, I understand that breadth is generally preferred over depth (at least in python, right?), uses the much-hated python ternary, and is 89 chars wide (plus probably more significant smells I don't even recognize).
I'm trying to:
- not declare pointless or temporary variables
- be concise
- avoid traditional loops
- avoid changing variables' values
I considered rewriting with a nested recursive function, would this make more sense? Also, if I'm using the term "functional" in the wrong way, or completely missing the point, please correct.
def getWordScore(word, n):
"""
Returns the score for a word. Assumes the word is a valid word.
The score for a word is the sum of the points for letters in the
word, multiplied by the length of the word, PLUS 50 points if all n
letters are used on the first turn.
word: string (lowercase letters)
n: integer (hand size required for additional points)
returns: int >= 0
"""
return len(word) * sum(map(lambda x: values[x], word)) + (50 if len(word)==n else 0)
