DeepDiff exclude_paths 正则表达式未过滤掉路径

Question

我有两个词典想使用 DeepDiff 进行比较，不包括 "items" 列表中的 "a" 键：

d1 = {"items": [{"a": 1, "b": 2}, {"a": 1, "b": 2}]}
d2 = {"items": [{"a": 10, "b": 2}, {"a": 100, "b": 2}]}

exclude_paths = [r"root\['items'\]\[\d+\]\['a'\]"]
diff = DeepDiff(d1, d2, exclude_paths=exclude_paths)
pprint(diff)

理想情况下，DeepDiff 应该报告一个空字典，但它报告的是 "a" 个值。

{'values_changed': {"root['items'][0]['a']": {'new_value': 10, 'old_value': 1},
                    "root['items'][1]['a']": {'new_value': 100,
                                              'old_value': 1}}}

我的 exlude_paths 正则表达式有什么问题吗？我正在关注 docs.

我尝试了 exlude_paths 的其他值，但没有成功：

r"root['items'][\d+]['a']"
r"root\[\'items\'\]\[\d\]\[\'a\'\]"

Answer 1

只需要使用 exclude_regex_paths 参数而不是 exclude_paths 参数：

d1 = {"items": [{"a": 1, "b": 2}, {"a": 1, "b": 2}]}
d2 = {"items": [{"a": 10, "b": 2}, {"a": 100, "b": 2}]}

diff = DeepDiff(d1, d2, exclude_regex_paths=[r"root\['items'\]\[\d+\]\['a'\]"])
pprint(diff)  # {}

DeepDiff exclude_paths 正则表达式未过滤掉路径

DeepDiff exclude_paths regex not filtering out paths
