🔒 (Repost) Program not accepted despite having info and giving the correct cost

[jolly nimbus]

I have tried multiple ways to compute the total cost but it still isn't accepting my work.

Code:

Author: 

Compute the total cost of video rental.

1. Significant constants
       cost of new videos
       cost of oldies
       
2. The inputs are
       number of new videos
       number of new oldies
3. Computations:
       total cost = number of new videos * 3.00 + number of oldies * 2.00 

4. The outputs are
       the total cost
"""
# Request the inputs
a=int(input("Enter the number of new videos: "))
b=int(input("Enter the number of oldies: "))

# Compute the cost
New=  a*3.00
Oldies = b*2.00

#Display the total cost
print("The total cost is $",New+Oldies)```

ah, you could just have posted the new image later in the chat
anyways, lets continue

what have you learned in school so far when it comes to python?

[jolly nimbus]

Sorry I get really dumb when stressed

Nothing too informative
We get examples of codes and key words but not how to apply them and when to use them

[amber merlin]

don't worry about it 🙂

[amber merlin]

ouch, okay, have you learned about concatenation of strings and type conversion? (i see that you are already doing a little bit of type conversion one way)
or f-strings?

[jolly nimbus]

Oh! I saw str in one of the pictures in my textbook
Didn't explain why or when to use it

[earnest tundra]

thats normal dw

[amber merlin]

str is a data type (which in python also means it's a class, but we don't need to go into details on that right now)
the important part here is that you can use it to "cast" (convert) something to that type as long as it's compatible and able to become a string

you are already doing something similar with the input() which always return (gives you) a string of text, but as you enclose it in int() you are trying to "cast" that string to an int (an integer, a whole number) if the string contains something that python thinks looks enough like an integer to be able to change it into that (or else you will get an error (in the form of an exception)

[jolly nimbus]

Omg it worked!!
I used
print("The total cost is $" + str(New+Oldies))

Do I just use this when calculating cost or is it needed for anything else?

[amber merlin]

this is called "explicit casting", there is also some "implicit casting" going on here, when you multiply the integer variable with a number that contains a decimal point (called a float) the answer will always be a float (so you get a decimal number back)

[amber merlin]

that is correct, that's one of several ways to solve this problem 👍

[odd stone]

try using functions to return values or make the result in string for ex:

print("Total : ", str(total))

or

print(f"Total : ${total}")

your code is fine but the debugger interpreter is working in a weird way

[amber merlin]

and the plus in-between two strings becomes the "concatenation" operator

[amber merlin]

i'm not sure OP has learned about f-strings yet

[jolly nimbus]

Not yet, but I'll keep it in mind!
If the course ever decides to be beginner friendly and mention it

Thank you all!

[amber merlin]

the first one you suggested is both invalid syntax (you forgot to close the parentheses for print()) and still have the original problem with getting a space in-between the strings

[amber merlin]

you're welcome, and you are always welcome back here on the server 🙂

also, good job in solving the problem mostly on your own

[odd stone]

my bad, I am using my phone rn

[amber merlin]

ah, i know how that can be ✅

[odd stone]

idk how some make whole projects coding with a phone

[jolly nimbus]

Aww thanks!
Mind if I close this after the convo is done?

[amber merlin]

you would have to start your own help thread if you have your own questions

[amber merlin]

it's your help thread, so you decide
take care 👋

[odd stone]

not really, thx tho

[jolly nimbus]

Take care!
