在上面的代码中,convert_to_4bit_int函数接受一个整数作为输入,并使用位与运算符(&)和二进制掩码(0b1111)来确保输出为4位整数。如果输入数据不在0到15的范围内,函数将引发ValueError异常。 序列图 下面是一个使用序列图描述上述代码的示例: 输入数据(9)转化为4位整数输出结果(9) ...
if the non-integer has a__index__()method then that method is called to convert the argument to an integer before packing. If no__index__()method exists, or the call to__index__()raisesTypeError, then the__int__()method is tried. However, the use of__int__()is deprecated, and...
