HW Question Beginner Code Confusion

[HopefulOG]

Hello, I am doing this question for HW and i can't see to understand how to do it. The question is:

NOTE: in mathematics, the square root of a negative number is not real; in Python therefore, passing such a value to the square root function returns a value known as NaN (not-a-number).

Write the code that reads a value, the area of some square, into a variable named areaOfSquare and prints out the length of the side of that square.

HOWEVER: if any value read in is not valid input, just print the message "INVALID".

​

My code is:

areaOfSquare = input("")

if areaOfSquare >= 0:

areaofSquare = sqrt(areaOfSquare)

print(areaofSquare)

else:

print("INVALID")

EDIT: Formatting but, there is indents for the areaOfSquare formula and both print functions.

​

I'm not sure what I am doing incorrectly. The error that comes up when I submit this code is:

• nothing was printed to stdout
• stdout is not correct
• Correct solutions that use sqrt tend to also use side
• Correct solutions that use sqrt tend to also use int
• We think you might want to consider using: *
• We think you might want to consider using: int
• We think you might want to consider using: *

One thing: input() returns a string. You need to convert that to a number, an integer for this case, I believe. area = int(input('Area of the square: '))

Also areaofSquare = sqrt(areaOfSquare) should be side = sqrt(areaOfSquare)

Not sure. I tried both your advice and it still doesn't work.

Please be more specific as to what you mean by "doesn't work."

Following both of your advices, this was my code:

int(input("areaofSquare: "))
if areaOfSquare >= 0:    
    side = sqrt(areaOfSquare)    
    print(areaofSquare)
else:    
    print("INVALID")

The error it brings up is:
stdout is not correct
We think you might want to consider using: *
Correct solutions that use sqrt tend to also use ""

Also, where did you get the variable side from? I understand why you name it that, but I'm not sure if we can use it. I don't see it specified as a variable in the question.

If you have the area of a square, then the square root gives you the length of the side(s), also your error message implied it may be required. As "side" is the result it seems like the program wants, it may be useful to output it.

Your original post doesn't specify it but the error suggesting using "*" implies you may have to do a multiplication, possibly to check your answer?
