def mean(data_set, index):
new_list = 
len_list = find_length(a_list)
sum_list = find_sum(a_list)
mean_list = sum_list / len_list
avg_price = mean(apps_data, 4)
The result is 4331 which is wrong, I am not even sure what I am calculating, anyone who can help me figuring this out? Thank you!
Pleas make sure your code is properly formatted and indented. You may use these guidelines to assist you.
Also not sure why you need to have a new list when the mean should just be a single value.
