I stuck in "Revenue Growth Analysis" in Python Data Structure

Question

Hi, I'm trying to solve Revenue Growth Analysis Project in Python Data Structure.
I don't understand why I try the example (In project description) and It's actually 20%.
But I don't know where 15000$ and 18000$ come from. Can someone explain?
My code:

Answer 1

Satakun Utama I think I was a little off earlier, it is 20$ rather than 20% discount.

But here is your code:
The problem is the second for loop, it is checking if equal to that age when it should be greater or equal, if >= age then add 20$ else add 5$.

Second, the program dont need to check if tcount is larger than count vice versa, you can just compare the two right away, to get negative values.

If you have more questions, please feel free to ask. Thanks.

Answer 2

Satakun Utama , 15000 and 18000 are just some numbers to demonstrate how they can be used in the formula given. but they have no real relation to the values in the data dict sample.
In addition to the method described (for loop and incrementing / summing variables), there are also other ways that can be applied to solve the task. if you are familiar with dicts, you could use a dict comprehension with a filter condition ( >=18) to get the number of tickets sold with regular price. together with the number of total items sold, it is possible to get the numbers of tickets sold with reduced price. it would be also possible to use the filter function with the data dict and a filter condition to get the numbers required for the final calculation.
so with 6 lines of code the task is done.
happy coding!

Answer 3

Hey, make count = 1 and tcount = 1 then it will work, I hope

Answer 4

age = int(input())
#your code goes here

def z (y):
count=0
count1=0

for x in data.values():
if x < y:
count += 1
else:
count1 += 1
return (count *5) + (count1 *20)

print(int((z(age)-z(18))/z(18) *100))

Answer 5

data = {
"100-90": 25, "42-01": 48, "55-09": 12, "128-64": 71, "002-22": 18, "321-54": 19, "097-32": 33, "065-135": 64, "99-043": 80, "111-99": 11, "123-019": 5, "109-890": 72, "132-123": 27, "32-908": 27, "008-09": 25, "055-967": 35, "897-99": 44, "890-98": 56, "344-32": 65, "43-955": 59, "001-233": 9, "089-111": 15, "090-090": 17, "56-777": 23, "44-909": 27, "13-111": 21, "87-432": 15, "87-433": 14, "87-434": 23, "87-435": 11, "87-436": 12, "87-437": 16, "94-121": 15, "94-122": 35, "80-089": 10, "87-456": 8, "87-430": 40
}
age = int(input())

teen = 0
lista = 0

for value in data.values():
if value < 18:
teen += 1

for value in data.values():
if value < age:
lista += 1

total_tickets = len(data)

menores_edad = teen
mayores_edad = total_tickets - teen
original_price = 20 * mayores_edad + 5 * menores_edad

menores_lista = lista
mayores_lista = total_tickets - menores_lista
total_price_discount = 5 * menores_lista + 20 * mayores_lista

print(int((( total_price_dis

Answer 6

This is my attempt so far , i don't know why it is considered wrong ?

total = 0
data = data.values()
for age in data:
if age < 18:
total += 5
else:
total += 20
print (total)
user_age = int(input())
new_total = total
for age in data:
if age < user_age:
new_total += 5
else:
new_total += 20
print (new_total)
revenue_growth = (new_total / total )*100
print (revenue_growth)
