print(nested_list[0][0:1]) # [1] 1. 2. 3. 在这个例子中,我们首先使用 nested_list[0:2] 来获取嵌套列表中前两个子列表。然后,我们使用 nested_list[0][0:1] 来获取第一个子列表中的第一个元素。 当然也可以使用负数索引和步长来更灵活地控制切片操作。例如: nested_list = [[1, 2], [3,...
the error is saying there is no intf attribute in service, that is because the intf list is nested inside the endpoints list. Stefano 5 Helpful Reply BasharAziz Level 1 In response to snovello 11-23-2020 02:45 AM Nested for loops in Python were needed. Awesome...

https://leetcode.com/problems/flatten-nested-list-iterator/ 展平嵌套的list。 从调用的方式来看,总会调用到最后,所以在构造函数中递归展开所有的数放到一位数组中。 另一种方式是把nested list压到栈中,需要的时候再从栈中拿。 注意需要调用注释中的isInteger(),getInteger()和getList()三个方法。
