我有
a={0: ['I3925'], 1: ['I3925'], 2: ['I3925'], 3: ['I2355'], 4: ['I2355'], 5: ['I2355'], 6: ['I111'], 7: ['I111'], 8: ['I111'], 9: ['I405'], 10: ['I405'], 11: ['I3878', 'I2864'], 12: ['I3878'], 13: ['I534'], 14: ['I534'], 15: ['I134', 'I2276'], 16: ['I107'], 17: ['I107'], 18: ['I2864']}
它包含一个密钥的一个补充的I号。在
^{pr2}$然后get_dummies就不起作用了,因为它创建了一个重复的列1_15来存储与第二个I号的匹配,而不是将它们堆叠到同一列中。我不明白为什么。在

有人能解释一下我做错了什么吗?在
