NOTE: in mathematics, the square root of a negative number is not real; in Python therefore, pa ssing 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 area0fsquare 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". Additional Notes: Regarding your code's standard output, CodeLab will check for case errors and will check whitespace (tabs, spaces, newlines) exactly.
