Check50 says I am returning '2' but I do not think this is the case. I have also tried changing the order in which I print/return to see if it is expecting something different the error messages are all the same. Bellow is the code and the check50 output

C_LIGHT = 300000000

def main():
    ##prompt the user for input
    ##assuming the user inputs integer per instructions
    user_in = int(input("Input a mass in kg to Calculate E=Mc^2\n"))
    print(mass_to_energy(user_in))

def mass_to_energy(user_in):
    ##Calculating e=mc^2
    ## outputs the equivalent number of Joules as an integer
    ##print(user_in * (C_LIGHT ** 2))
    return (user_in * (C_LIGHT ** 2))

main()
