# Dictionary and Frequency Tables Mission

``````    opened_file = open('AppleStore.csv')

rating_count_tot = []

for row in apps_data[1:]:
rating = float(row)
rating_count_tot.append(rating)

max_rating = max(rating_count_tot)
min_rating = min(rating_count_tot)

rating_buckets = {'0 - 100,000': 0, '100,000 - 1,000,000': 0, '1,000,000 +' :0}

for rating in rating_count_tot:
if rating <= 100000:
rating_buckets['0 - 100,000'] += 1
if 10000 < rating <= 1000000:
rating_buckets['100,000 - 1,000,000'] += 1
if rating > 1000000:
rating_buckets['1,000,000 +'] += 1

values = rating_buckets.values()
total = sum(values)

print(len(rating_count_tot))
print(total)
``````

What I expected to happen:

For these two variables to return the same value:

print(len(rating_count_tot))
print(total)
What actually happened:

``````7197
7995
``````

Essentially, I was testing to make sure that my list of ratings would be equal to the sum of the different buckets in my frequency breakdown. This way I would be sure that I did the code correctly and accounted for all the ratings.

Any idea why the number is coming out differently?

Thanks!

Hi @alvand.hajizadeh. It looks like you have an overlap here due to a missing zero:

``````    if rating <= 100000:                         # 100,000
rating_buckets['0 - 100,000'] += 1
if 10000 < rating <= 1000000:                # 10,000
``````

Once you fix this you should get an accurate count. 1 Like

ah I see. Thank you so much!
