Pls What is wrong with this code

Question

choice = input("What Operation do you want to perform(Add,Subtract,Divide,Multiply)")
add_x = float(input("Enter Number 1:")
add_y = float(input("Enter Number 2:")
subtract_x = float(input("Enter Number 1:")
subtract_y = float(input("Enter Number 2:")
divide_x = float(input("Enter Number:")
divide_y = float(input("Enter Number 2:")
multiply_x = float(input("Enter Number 1:")
mulitiply_y = float(input("Enter Number 2:")
if choice == "Add":
result = (add_x + add_y)
print(z)
elif choice == "Subtract":
result = (subtract_x - subtract_y)
print(z)
elif choice == "Divide":
result = (divide_x / divide_y)
print(z)
elif choice == "Multiplication":
result = (multiply_x * multiply_y)
print(z)

Answer 1

Isabel You are right about 2 and 3.

As for 1, after input of choice the code continues with reading the numbers, so when reaching the if/elif it will have all the values it needs.

As a recomandation: is to move the input of numbers inside the cases so that he reads only 2 numbers. It doesn't need to read 8 numbers and to calculate only with two.

Edit:
Or to read only two numbers before and to perform on those the chosen operation.

Answer 2

Isabel You're welcome.

We solved the problem and agreed on everything.

Though it seems the OP "left the building" a while ago.

Answer 3

There are 3 possible issues:

1. After the first input prompt, after readers choose add, subtract, etc, your code responds with result = (equation). You are missing a step in between, where you ask readers to provide values for add_x, etc, so the code is trying to calculate information that it does not have.

2. All of your float(input)) are missing the second ) on the right side.

3. If you use “result =“ to save the results of your calculations, your code will not be able to print(z). You have never told it what z means.

(All of these are problems I have all the time. So much of learning to code is learning to pay attention to details!)

Answer 4

You only need three inputs:
1. the choice...
2. the first number...
3. the second number.

Answer 5

Mihai I copied the code above into Code Playground and got “error parsing EOF” when it tried to read the float variables. Is it because Code Playground doesn’t support a second dialog box for user input?

Answer 6

Isabel

Short answer: yes, in Playground all inputs are delivered before execution of code.

Long answer:
After adding missing paranthesis and replacing variables z with result or result with z, it should:

In Playground:
Input all data on separate lines
Eg.
Add
1
2
3
4
5
5
6
7
8
and then SUBMIT

In IDE:
Input data as prompted.
Eg.
Add return; 1 return; 2 return; 3 return;.....8 return
return as in enter key

Answer 7

Thank you, Mihai

I stripped the code down to this and it did run on Code Playground.

choice = input("What Operation?")
x = float(input("Enter Number 1:"))
y = float(input("Enter Number 2:"))
if choice == "Add":
z = (x + y)
print(z)
elif choice == "Subtract":
z = (x - y)
print(z)
elif choice == "Divide":
z = (x / y)
print(z)
elif choice == "Multiplication":
z = (x * y)
print(z)

Answer 8

You are missing some paranthesis when reading the numbers.

Answer 9

You are storing the results in the result variable but you are printing z.

And I recomend to move the input statements 2 by 2 into the if/elif cases.

Answer 10

Is that all

Answer 11

I don't know much about Python, but as I understand your code correctly, it should be print(result).

Answer 12

Hello KateJ. There are many issues in the code in the post/question. You can sort the answers by date and read them. In the end you will find a working code snippet by Isabel.
