My python issues

Question

EDIT: Ill change the thread to contain more questions if I run in to more issues, instead of creating a new thread each time :-)

My initial question
continue

You are making a ticketing system.
The price of a single ticket is $100.
For children under 3 years old, the ticket is free.

Your program needs to take the ages of 5 passengers as input and output the total price for their tickets.

Sample Input
18
24
2
5
42

Sample Output
400

Ive tried 2 different things and nothings seems to work

total = 0
ticket = 0
cal = int(input())
i = 0
while i < 6:
cal = int(input())
if cal < 3:
ticket = 0
else:
ticket = 100
total += ticket
i +=1
print(total)

#for x in cal:
# print(x)

# cal = input()
# cal = int(cal)
# if cal < 3:
# ticket = 0
# else:
# ticket = 100
# total += ticket

#print(total)

thank you in advance for inputs

Answer 1

I succeed with a different approach

total = 0
#your code goes here
ticket = 0
i = 0
while i < 5:
x = int(input())
if x < 3:
ticket = 0
elif x >= 3:
ticket = 100
total += ticket
i +=1
print(total)

But can this solution be made with out defining that i has to be under 5

Answer 2

Rik Wittkopp No worries, been there done that a few times myself. 😁😁

Answer 3

ChaoticDawg its the python beginner course - > Control flow - > break & continue

Answer 4

Kristian Sørensen
So, given the current lessons and stage at which this course is for this Pro code coach challenge, I believe the intent is to use the continue statement to skip over adding the $5 price of a ticket for those that are under 3 years of age. As for getting the inputs the way you are doing so is fine and correct for this stage in the lessons. You won't need the ticket variable when using the continue statement.

Answer 5

Kristian Sørensen
You really should have made a new thread in the Q&A for this, but anyway all you need to do in the calc(x) function is calculate the perimeter and the area and return the values as a tuple.
p = side * 4
a = side * side
return p, a

Answer 6

That's because in your function you have x as the parameter not side which is what you are using and then you are setting the tuple to x within the function and not returning it. Change x to side (or use it correctly on the right of the = for the calculations in place of side) and make sure you return the tuple. Also, a square has 4 sides and your calculations are assigned to the wrong variables (swap them). See my small code example.

Answer 7

Allan QBit
I didn't say it wouldn't run or give the correct output. The only reason it works is because 'side' is a global variable. Look at your calc() function and the parameter vs the variable used. The way you have it there is no point in even having the function.

Answer 8

Allan QBit
Let you check what out?
Just change your calc() function so the in the body of the function side is x. Instead of using side globally. Then it will be correct.

Answer 9

Thanks ChaoticDawg
I will pull the response as you are correct that I did not read through.

Answer 10

Kristian Sørensen To answer the question "But can this solution be made with out defining that i has to be under 5", the answer is yes. You would need to initialize i=1 rather than i=0. For example, in your question the first code example is looping 6 times (0 - 5) but there are only 5 inputs. That is why <6 is an issue. But if you simply adjust i=1 the test of less than <6 is correct.

Hope that helps.

Answer 11

@ChaoticDawg Will create another one next time!

Ive tried something like this but i get an error on line 8 "p,a = calc(side)"
def calc(x):
#your code goes here
area = side*3
peri = side*side
x = (peri, area)

side = int(input())
p, a = calc(side)

print("Perimeter: " + str(p))
print("Area: " + str(a))

Answer 12

#should help here
def calc(side):
p=side*4
a=side*side
return p,a

side = int(input())
p, a = calc(side)

print("Perimeter: " + str(p))
print("Area: " + str(a))

Answer 13

Allan QBit
Your answer is incorrect. Take another look at it. Besides, I'm pretty sure that the it has been resolved already.

Answer 14

ChaoticDawg try running it

Answer 15

ChaoticDawg cool let me check it out

Answer 16

Rik Wittkopp you may want to re-read the question and see how the inputs are given.

Kristian Sørensen it may help to add where this code coach is from (which tutorial) and its lesson number, so we can see what has been taught so far. So, we don't give you an initial answer that is beyond what you have had the opportunity to learn so far.

Answer 17

Ive since progressed to the intermediate course and run in to a new problem:

path python intermedia->collection types -> tuple unpacking -> pro code coach -> square up.

Im given this:
Tuple Unpacking

Tuples can be used to output multiple values from a function.
You need to make a function called calc(), that will take the side length of a square as its argument and return the perimeter and area using a tuple.
The perimeter is the sum of all sides, while the area is the square of the side length.

Sample Input:
3

Sample Output:
Perimeter: 12
Area: 9

and Im given this code:

def calc(x):
#your code goes here

side = int(input())
p, a = calc(side)

print("Perimeter: " + str(p))
print("Area: " + str(a))

Im quite lost on how to approach this, my initial thought is to read up on classes and functions, otherwise I dont understand where to begin with this one, any help is appreciated.

Answer 18

i=1
f=0
while i<=5:
i=i+1
age=int(input())
if age<3:
continue
f=f+100
print(f)

Answer 19

total = 0
#your code goes here
ticket = 0
limit=0
while limit <= 4:
x = int(input())
if x < 3:
total = total
elif x >= 3:
total += 100
limit +=1
print(total)

Answer 20

def calc(x):
#your code goes here
p = x*4
a = x**2
return [p, a]

side = int(input())
p, a = calc(side)

print("Perimeter: " + str(p))
print("Area: " + str(a))
