为什么不对

import math def quadratic_equation(a, b, c): d=b*b-4*a*c if d>= 0: x1 = (-b+math.sqrt(d))/(2*a) x2 = (-b-math.sqrt(d))/(2*a) return x1,x2 else: return print quadratic_equation(2, 3, 0) print quadratic_equation(1, -6, 5) 为什么提示不正确

import math
def quadratic_equation(a, b, c):
    d=b*b-4*a*c
    if d>= 0:
        x1 = (-b+math.sqrt(d))/(2*a)
        x2 = (-b-math.sqrt(d))/(2*a)
        return x1,x2
    else:
        return
print quadratic_equation(2, 3, 0)
print quadratic_equation(1, -6, 5)

是否是因为缩进导致的？我运行你的代码有结果。
