import math as m

def main():
    a = int(input("a="))
    b = int(input("b="))
    c = int(input("c="))
    deta = int(b * b - 4 * a * c);

    if(deta >= 0):
        x1 = (-b + m.sqrt(deta))/(2 * a)
        x2 = (-b - m.sqrt(deta))/(2 * a)
    else:
        x1 = x2 = "no key"

    print("x1=", x1)
    print("x2=", x2)

if __name__ == '__main__':
    main()

输出：

a=10
b=52
c=65
x1= -2.0900980486407215
x2= -3.1099019513592787
