Python:仅打印二次方程的容差范围内的结果

import math

def print_quadratic_equation_results(a, b, c, tolerance):
    discriminant = b**2 - 4*a*c

    if discriminant < 0:
        print("No real solutions")
    elif discriminant == 0:
        x = -b / (2*a)
        print("Single solution:", x)
    else:
        sqrt_discriminant = math.sqrt(discriminant)
        x1 = (-b + sqrt_discriminant) / (2*a)
        x2 = (-b - sqrt_discriminant) / (2*a)
        
        if abs(x1 - x2) <= tolerance:
            print("Double solution:", x1)
        else:
            print("Two solutions:", x1, x2)
