第五行m=(-b+math.sqrt(t))/(2*a)少了一個回括號,加上回括號后跑出結果了.

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