Python Data Structures Fancy Houses Task Question

Question

Hey Guys I have a Problem. I think my code solves the problem, but i can not pass because sololearn shows that my answer is not correct and I can not look what is wrong because the case is closed. Maybe some of you guys could pass the task and find the problem.

Task:
You are analyzing house prices. The given code declares a list with house prices in the neighborhood.
You need to calculate and output the number of houses that have a price that is above the average.

To calculate the average price of the houses, you need to divide the sum of all prices by the number of houses.

My solution:

prices = [125000, 78000, 110000, 65000, 300000, 250000, 210000, 150000, 165000, 140000, 125000, 85000, 90000, 128000, 230000, 225000, 100000, 300000]
#your code goes here
average_price = int(sum(prices))/int(len(prices))
# print(int(average_price))
for n in prices:
if n < int(average_price):
prices.remove(n)
print(len(prices))

Average Price: 159777
Output (Number of houses above the average price): 11

Sorry for the long post

Answer 1

oh...You are changing original list by prices.remove(N) so there it skipping next iteration value for n in
for n in prices:
Alternatively use new list to modify or to add. Else take copy in loop as
for n in prices.copy():

Answer 2

Looking at your code, there is a problem. There are only 7 values above average. You already got the average and you have the list of numbers:

num_abv_avg = len([p for p in prices if p > average_price])

Answer 3

I think, May there need <= instead of <.

Answer 4

prices = [125000, 78000, 110000, 65000, 300000, 250000, 210000, 150000, 165000, 140000, 125000, 85000, 90000, 128000, 230000, 225000, 100000, 300000]
#your code goes here
average_price = sum(prices)/len(prices)
# print(int(average_price))
for n in prices[:]: #MODIFIED PART
if n < int(average_price):
prices.remove(n)
print(prices,len(prices))

Do this instead.. It'll work for sure..
Should be very careful while using the remove()

Answer 5

Ohh yeah thanks

Answer 6

This one worked out. Thanks @slick

prices = [125000, 78000, 110000, 65000, 300000, 250000, 210000, 150000, 165000, 140000, 125000, 85000, 90000, 128000, 230000, 225000, 100000, 300000]
#your code goes here
average_price = sum(prices)/len(prices)

num_abv_avg = len([p for p in prices if p > average_price])

print(num_abv_avg)

Answer 7

Thanks for your anser but this should not change the output of the code

Answer 8

I will try thanks))

Answer 9

11 is not right, look at the prices there are only 7 with higher price than 159777.

Take new variables to avoid to change the original list:

num_high_price = 0
for i in prices:
if i >= average:
num_high_price += 1
print(num_high_price)
