【问题描述】：

我想从字典中随机选择 2 个字典，它们的值 [0] == 'C'。

d = {"1": ('B', [3, 4, 8]), "2": ('C', [2, 6, 8]), "3": ('C', [9, 10, 11, 13]), "4": ("E", [14, 15, 16, 17]), "5": ("C", [20])}
for key, val in d.items():
        if val[0] == 'B':

            b = val[0] == 'C'
            res = key, val = random.choice(list(d.items()))
            print(res)

e = {"2": ('C', [2, 6, 8]), "3": ('C', [9, 10, 11, 13])}
e = {"2, 3": ('C', [2, 6, 8] , [9, 10, 11, 13])}

【解决方案1】：

如果您希望选择的 2 个元组彼此不同，请尝试以下操作：

>>> dict(random.sample([(k, v) for k, v in d.items() if v[0] == "C"], 2))
{'5': ('C', [20]), '3': ('C', [9, 10, 11, 13])}
