在Python列表理解中可以访问项目索引吗?

问题描述:

考虑以下Python代码,我将新的 list2 中所有索引从1到3的项添加到新的 list2 中:

Consider the following Python code with which I add in a new list2 all the items with indices from 1 to 3 of list1:

for ind, obj in enumerate(list1):
    if 4 > ind > 0:
        list2.append(obj)

如果我无法通过枚举访问索引,您将如何使用列表理解来编写此代码?

How would you write this using list comprehension, if I have no access to the indices through enumerate?

类似:

list2 = [x for x in list1 if 4 > ind > 0]

但是因为我没有 ind 号码,这行得通吗?

but since I have no ind number, would this work?

list2 = [x for x in enumerate(list1) if 4 > ind > 0]

list2 = [x for ind, x in enumerate(list1) if 4 > ind > 0]
