我想从以下json输出中提取第一个定义值。另外，逐行打印所有定义值也是很好的。

我正在用这样的东西读取输出：
oxford_dict = json.loads(oxford_output)
print(oxford_dict['metadata']['provider'])
但是我不确定如何进一步深入挖掘并获取第一个定义，因为它存在多次。
答案 0 :(得分：1)
你有一个多嵌套词典。
尝试：
for i in oxford_dict["results"]:
for j in i["lexicalEntries"]:
for k in j["entries"]:
for v in k["senses"]:
print(v["definitions"])
<强>输出：
['a playing card with a single spot on it, ranked as the highest card in its suit in most card games']
['a person who excels at a particular sport or other activity']
['(in tennis and similar games) a service that an opponent is unable to return and thus wins a point']
['a person who has no sexual feelings or desires']
['very good']
['(of a person) having no sexual feelings or desires; asexual']
['(in tennis and similar games) serve an ace against (an opponent)']
['achieve high marks in (a test or exam)']
