代码如下：
#coding=utf-8#python - 列表分组技巧#请写出一段 Python 代码实现分组一个 list 里面的元素,如 [1,2,3,...100]变成 [[1,2,3],[4,5,6]....]a = [x for x in range(1,101)]b = [a[i:i+3] for i in range(0, len(a),3)]print(b)运行结果：
[[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12], [13, 14, 15], [16, 17, 18], [19, 20, 21], [22, 23, 24], [25, 26, 27], [28, 29, 30], [31, 32, 33], [34, 35, 36], [37, 38, 39], [40, 41, 42], [43, 44, 45], [46, 47, 48], [49, 50, 51], [52, 53, 54], [55, 56, 57], [58, 59, 60], [61, 62, 63], [64, 65, 66], [67, 68, 69], [70, 71, 72], [73, 74, 75], [76, 77, 78], [79, 80, 81], [82, 83, 84], [85, 86, 87], [88, 89, 90], [91, 92, 93], [94, 95, 96], [97, 98, 99], [100]]阅读全文
