while continue in LIST

Question

hi all
I try to do the example proposed in while loops lesson,
###An example use case of continue:
An airline ticketing system needs to calculate the total cost for all tickets purchased. The tickets for children under the age of 1 are free. We can use a while loop to iterate through the list of passengers and calculate the total cost of their tickets. Here, the continue statement can be used to skip the children.###
but I can't find the good code, if someone can help me I will be very thankful :D there is the code i made Intel know :( sorry for my English not very good )

coste_age =[20,2,58,1,89,56,1]
x=len(coste_age)
i=0
while i<x:
if cost_age[i] <=1:
continue
print (cost_age[i])
i+=1

print (coste_age[i]) i+=1

Answer 1

The indentation is off which will mess up the Python.

What is the cost for people over 1 year of age?

Assuming the cost of each ticket for someone over 1 year of age is $1, this will work:
cost_age =[20,2,58,1,89,56,1]
x=len(cost_age)
i=-1
total_cost = 0
while i < x - 1:
i += 1
if cost_age[i] <= 1:
continue
total_cost += 1

print('Total cost for all tickets is: $%d.' % total_cost)

My interpretation of this statement is that only babies under 1 year of age are free: "The tickets for children under the age of 1 are free" In other words, it would be "cost_age[i] < 1" instead of "cost_age[i] <= 1".

If you weren't encouraged to use a while-loop, I would use a for-loop instead like this to avoid defining variable i.
cost_age =[20,2,58,1,89,56,1]
total_cost = 0
for age in cost_age:
if age <= 1:
continue
total_cost += 1

print('Total cost for all tickets is: $%d.' % total_cost)
