import math def check(*x): for i in x: if not isinstance(i,(int,float)): raise TypeError('bad operand type')

def quadratic(a,b,c): check(a,b,c) xx = b*2-4ac if a == 0: return -c/b elif xx < 0: return 'No Solution' else: x1 = (-b+math.sqrt(xx))/(2a) x2 = (-b-math.sqrt(xx))/(2*a) return x1,x2

跑步不要回头看啦

要加好多运算符号。。。

a牵挂a

提问： import math def calc(a,b,c): deta = bb - 4ac if(a < 0): return 'input error' elif(deta < 0): return 'input error' else: x1 = (-b+math.sqrt(deta))/2a x2 = (-b-math.sqrt(deta))/2*a return x1,x2

from def_function import calc tu = calc(1,-5,6) print(tu)

函数和使用都在这个def_function文件，但是加入一个import后，结果输出两次 (3.0, 2.0) (3.0, 2.0)
