Question

所以我不会撒谎，这是一项家庭作业。我试图在字典中找到最大值：

scores = dict()
scores['Andy'] = 78
scores['Bill'] = 82
scores['Cindy'] = 94
scores['Dave'] = 77
scores['Emily'] = 82
scores['Frank'] = 94
scores['Gene'] = 87

max_val = max(scores, key=scores.get)
print(max_val)

我需要打印出Cindy和Frank的名字，以显示它们具有最大值，但它只打印出名字（Cindy）。如何打印第二个呢？我确定这将是一个非常简单的答案，但请不要将我钉在十字架上。我还是比较新的。

Answer 1

您已找到最大值。现在只需比较：

max_vals = [x for x, v in scores.items() if v == scores[max_val]]
print(max_vals)

>>> ['Cindy', 'Frank']

Answer 2

只需将其添加到print语句中，比较每个键的值以查找最大值：

scores = dict()
scores['Andy'] = 78
scores['Bill'] = 82
scores['Cindy'] = 94
scores['Dave'] = 77
scores['Emily'] = 82
scores['Frank'] = 94
scores['Gene'] = 87

max_val = max(scores.values())
print(scores)
print ([k for k,v in scores.items() if v == max_val])

Python字典中的最大值
