Python 可以在字节串上执行类似字符串的格式化某些操作了吗?

    (问题来自 Cookbook.Page 82) 例如:

    try:
    test = b'%10s %10d %10.2f' % (b'ACME',100,490.1)
    except TypeError:
    print('不能子啊字节串上执行类似字符串的格式化操作')
    else:
    print(test)

    执行结果:b' ACME 100 490.10'

    但是 Cookbook 的 traceback 是‘ TypeError ’,这是为什么? Python 3.x 从哪个版本做修改了吗?
    (一点值得注意,Byte String 还是不能执行.format()操作)
