在遍历list,删除符合条件的数据时,总是报异常,代码如下: num_list = [1, 2, 3, 4, 5] print(num_list) for i in range(len(num_list)): if num_list[i] == 2: num_list.pop(i) else: print(num_list[i]) print(num_list) 会报异常:IndexError: list index out of range 原因是在删除list中的元素后,list的实际长度变
比如我将string作为CNN 文本处理输入: float [] input = new float[maxLength]; // 1 sentence by maxLenWords // int[] input = new int[batchSize * maxLength]; // 1 sentence by maxLenWords int i = 0; final int length = subdomain.length(); for (int offset = 0; offset <
先放一个python遍历发生的异常: ls =[1,2,3,4,5,6,7,8,9] for i in ls: print("i",i) print("ls",ls) ls.remove(i) 运行结果: i 1 ls [1, 2, 3, 4, 5, 6, 7, 8, 9] i 3 ls [2, 3, 4, 5, 6, 7, 8, 9] i 5 ls [2, 4, 5, 6, 7, 8, 9] i 7 ls [2, 4, 6, 7, 8, 9] i 9 ls [2,
