I am fairly new to python 3. Is there a way to implement a +/- function into a single line of code? In this simple quadratic formula solver function I wrote, I used two separate variables and returned them both. Is there a cleaner way to do this?

def Quadratic_Solver(a,b,c):      """     This function returns solution to a univariate (single variable)       quadratic equation 0 = ax2 + bx + c, where a is not 0.      Args:      * a (float or int) - the value represents coefficient of degree                        variable 2      * b (float or int) - the value represents coefficient of degree                       variable 1      * c (float or int) - the value represents the constant      Returns:      * two solutions for x (float)      """     try:         a = float(a)         b = float(b)         c = float(c)         sol1 = (-b + (b**2 - 4*a*c)**0.5)/(2*a)         sol2 = (-b - (b**2 - 4*a*c)**0.5)/(2*a)         return (sol1, sol2)      except:         print("Input variables are not floats")
