Tóm tắt: Danh sách toàn diện được thiết kế xung quanh các vòng lặp hơn là trong khi vòng lặp, vì vậy đây không phải là một sự phù hợp tốt. List comprehensions are designed around for-loops rather than while-loops, so this isn't a good fit.
Những gì cần thiết: vòng lặp for yêu cầu một trình lặp cho đầu vào. The for-loop requires an iterator for input.
Thay thế 1: Điều này có thể hoạt động với sự hiểu biết danh sách, nhưng điều đó sẽ đòi hỏi phải chuyển công việc thành một trình tạo (có khả năng không phải là những gì bạn đang hy vọng): This could work with a list comprehension, but that would entail shifting the work into a generator (which likely isn't what you were hoping for):
>>> child = {'a':'b', 'b': 'c', 'c': 'd', 'd': None} >>> def ll_iterator(node): while node != None: yield node node = child[node] >>> [x for x in ll_iterator('a')] ['a', 'b', 'c', 'd']Thay thế 2: Bên cạnh các máy phát điện, một cách khác để tạo một trình lặp là sử dụng hai dạng đối số của iter (). Để hoạt động, bạn sẽ cần một chức năng không có trạng thái, không phát ra các nút danh sách liên kết liên tiếp: Besides generators, another way to make an iterator is to use the two argument form of iter(). For that to work, you would need a stateful, zero-argument function that emitted successive linked list nodes:
>>> child = {'a':'b', 'b': 'c', 'c': 'd', 'd': None} >>> def next_ll(state=['a']): value = state[0] if value is not None: state[0] = child[value] return value >>> [x for x in iter(next_ll, None)] ['a', 'b', 'c', 'd']Đánh giá: Cả hai lựa chọn thay thế này đều hơi thô thiển, vì vậy bạn tốt hơn nếu không có sự hiểu biết danh sách. Mã đơn giản, đơn giản là tốt nhất :-) Both of these alternatives are a bit gross, so you're better-off without the list comprehension. Simple, straight-forward code is the best :-)
Chú thích: Câu hỏi này là một câu hỏi hay. Nhiều hơn một người đã gợi ý rằng ngôn ngữ bổ sung trong khi vòng lặp vòng lặp. Nếu đề xuất đó từng đến với kết quả, việc áp dụng các biểu thức chuyển nhượng của Python 3.8 cũng sẽ giúp cho trường hợp sử dụng của bạn. This question is a good one. More than one person has suggested that the language add while-loop comprehensions. If that suggestion ever came to fruition, Python 3.8's adoption of assignment expressions would also help for your use case.
