自定义函数multi（）实现多个数求积

# multiply 
def multi(a):
    s=1
    for i in a:
        s*=i
    return s
def inp():
    a=input(‘please input nums(split with comma):‘)
    return a
if __name__==‘__main__‘:
    try :
        a=inp()
        result=multi(eval(a)) 
        print (‘the result of multipling is :‘,result)
    except:
        print ("please input with the correct information")
    finally :
        print (‘thanks‘)
