你应该把÷0的情况算在elif里了

and的优先级更高

把两个的顺序换一下，把最后一个改成else

a = input().split()
b = int(a[0])
c = int(a[1])
d = a[2]
if d != '+' and d != '-' and d != '/' and d != '*':
    print('Invalid operator!')
elif c == 0 and d == '/':
    print('Divided by zero!')
else:
    if d == '+':
        a = b+c
        print("%.0f"%a)
    if d == '-':
        a = b-c
        print("%.0f"%a)
    if d == '*':
        a = b*c
        print("%.0f"%a)
    if d == '/':
        a = b/c
        print("%.0f"%a)
