Calculate the discriminant valueΒΆ

Calculate the discriminant value.
Note:
The discriminant is the name given to the expression that appears
under the square root (radical) sign in the quadratic formula.
Test Data:
The x value : 4
The y value : 0
The z value : -4
Expected output:
Two Solutions. Discriminant value is : 64.0
def discriminant():

    x_value = float(input('The x value: '))
    y_value = float(input('The y value: '))
    z_value = float(input('The z value: '))

    discriminant = (y_value**2) - (4 * x_value * z_value)

    if discriminant > 0:
        print('Two Solutions. Discriminant value is:', discriminant)
    elif discriminant == 0:
        print('One Solution. Discriminant value is:', discriminant)
    elif discriminant < 0:
        print('No Real Solutions. Discriminant value is:', discriminant)

# test
discriminant()

Output:

The x value: 4
The y value: 8
The z value: 2
Two Solutions. Discriminant value is: 32.0
