您可以使用<a href="https://docs.python.org/3/tutorial/datastructures.html#list-comprehensions" rel="nofollow noreferrer">list comprehension</a>： <pre><code>d = {'results': [{'id': 654959, 'title': 'Pasta With Tuna', 'image': 'https://spoonacular.com/recipeImages/654959-312x231.jpg', 'imageType': 'jpg'}, {'id': 511728, 'title': 'Pasta Margherita', 'image': 'https://spoonacular.com/recipeImages/511728-312x231.jpg', 'imageType': 'jpg'}, {'id': 654812, 'title': 'Pasta and Seafood', 'image': 'https://spoonacular.com/recipeImages/654812-312x231.jpg', 'imageType': 'jpg'}, {'id': 654857, 'title': 'Pasta On The Border', 'image': 'https://spoonacular.com/recipeImages/654857-312x231.jpg', 'imageType': 'jpg'}, {'id': 654883, 'title': 'Pasta Vegetable Soup', 'image': 'https://spoonacular.com/recipeImages/654883-312x231.jpg', 'imageType': 'jpg'}, {'id': 654928, 'title': 'Pasta With Italian Sausage', 'image': 'https://spoonacular.com/recipeImages/654928-312x231.jpg', 'imageType': 'jpg'}, {'id': 654926, 'title': 'Pasta With Gorgonzola Sauce', 'image': 'https://spoonacular.com/recipeImages/654926-312x231.jpg', 'imageType': 'jpg'}, {'id': 654944, 'title': 'Pasta With Salmon Cream Sauce', 'image': 'https://spoonacular.com/recipeImages/654944-312x231.jpg', 'imageType': 'jpg'}, {'id': 654905, 'title': 'Pasta With Chickpeas and Kale', 'image': 'https://spoonacular.com/recipeImages/654905-312x231.jpg', 'imageType': 'jpg'}, {'id': 654901, 'title': 'Pasta With Chicken and Broccoli', 'image': 'https://spoonacular.com/recipeImages/654901-312x231.jpg', 'imageType': 'jpg'}], 'offset': 0, 'number': 10, 'totalResults': 210} titles = [i['title'] for i in d['results']] print(titles) </code></pre> 输出： <pre><code>['Pasta With Tuna', 'Pasta Margherita', 'Pasta and Seafood', 'Pasta On The Border', 'Pasta Vegetable Soup', 'Pasta With Italian Sausage', 'Pasta With Gorgonzola Sauce', 'Pasta With Salmon Cream Sauce', 'Pasta With Chickpeas and Kale', 'Pasta With Chicken and Broccoli'] </code></pre> 说明： <ol> <li>首先，列表理解的工作方式如下：</li> </ol> <code>[i for i in d['results']]</code>返回与<code>d['results']</code>相同的结果 <ol start=“2”> <li>现在，您需要<code>d['result']</code>列表中每个字典的<code>'title'</code>键的值，因此将<code>i</code>更改为<code>i['title']</code>：</li> </ol> <code>[i['title'] for i in d['results']]</code>
