a) def 在Python中,声明函数的关键字是`def`,后接函数名和参数列表。选项分析如下:- **a) def**:正确。`def`是Python中定义函数的标准关键字。- **b) function**:错误。`function`不是Python语法,其他语言如JavaScript才会使用该关键字。- **c) define**:错误。Python不使用`define`声明函数,该词可能源...
DECLARE a(2,3)声明了一个二维数组:1. **维度解析**:第一维为2(元素索引可能是0-1或1-2),第二维为3(元素索引可能是0-2或1-3)。2. **默认下界**:多数编程语言(如C、Python)默认数组索引从0开始。若索引为0-1和0-2: - 第一维度元素数量为2(0,1) - 第二维度元素数量为3(0,1,2)3. **...
