3.for + range # 控制循环的次数 range 会自动生成一个列表,来表中的值的个数代表循环几次(顾头不顾尾) name = 'JAKE' #for + break / for + else 和while一样 没有区别 sercrt = 'asd' for a in range (3): inp_name = input('请输入你的账号:') inp_password = input('请输入你的密码:...
for i in range(4): d = i * 2 print(d) 1. 2. 3. 发现在for循环结束后d可见、可访问,会让你吃惊吗?不,这是Python工作的方式。因此,为什么要不同对待索引变量呢? 顺便提一下,在Python 3出现前,列表推导(list comprehension)的索引变量也泄露进了围合(enclosing)的作用域。 Python 3修复了列表推导的...
Index range = Indices.range(index, index + 1);// 切片的起始和结束索引 ByteNdArray validationImage = trainingImages.slice(range); // 执行切片操作 ByteNdArray validationLable = trainingLabels.slice(range); // 执行切片操作 if (index >= 0) { return new MnistDataset(trainingImages,trainingLabels,...
它的实现是这样的。 public static int[] range(int start,int end,int step){ int sz =(end-start)/step; int[] result=new int[sz]; for(int i=0;i<sz;i++) result[i]=start+(i*step); return result; } 这样的话我range(1,10,2),得到的是{1,3,5,7}这样的数组, 但我看到python中ra...
