Function for averages of tuples in a dictionary
- by Billy Mann
I have a string, dictionary in the form:
('the head', {'exploded': (3.5, 1.0), 'the': (5.0, 1.0),
"puppy's": (9.0, 1.0), 'head': (6.0, 1.0)})
Each parentheses is a tuple which corresponds to (score, standard deviation). I'm taking the average of just the first integer in each tuple. I've tried this:
def score(string, d):
for word in d:
(score, std) = d[word]
d[word]=float(score),float(std)
if word in string:
word = string.lower()
number = len(string)
return sum([v[0] for v in d.values()]) / float(len(d))
if len(string) == 0:
return 0
When I run:
print score('the head', {'exploded': (3.5, 1.0), 'the': (5.0, 1.0),
"puppy's": (9.0, 1.0), 'head': (6.0, 1.0)})
I should get 5.5 but instead I'm getting 5.875.
Can't figure out what in my function is not allowing me to get the correct answer.
