Question

我有几个列表如下：

l1=['InitialRequest','Approved','WorkStarted','OnHold','InProgress','OnHold','InProgress','Completed']

l2=['InitialRequest','Approved','WorkStarted','OnHold','OnHold','OnHold','OnHold','Cancelled']

l3=['InitialRequest','Approved','WorkStarted','InProgress','InProgress','InProgress','InProgress','Completed']

...到l7。我需要维护列表中给出的序列，并生成每个列表15000次。所以我创建了这些列表的列表：

Status=[l1,l2,l3,l4,l5,l6,l7]

我试过这个：

Status_b = list(np.random.choice(Status, 15000, replace=True, p=[0.1,0.02,0.5,0.08,0.03,0.07,0.1,0.1]))

但是我收到以下错误：

Traceback (most recent call last):

 File "<ipython-input-168-d6488b73dd38>", line 1, in <module>
   Status_b = list(np.random.choice(Status, 15000, replace=True, p=[0.1,0.02,0.5,0.08,0.03,0.07,0.1,0.1]))

 File "mtrand.pyx", line 1117, in mtrand.RandomState.choice

ValueError: a must be 1-dimensional

有人可以给我一个解决方案吗？

Answer 1

而不是让random从列表中选择，让它选择索引：

weights = [0.1,0.02,0.5,0.08,0.03,0.07,0.1,0.1]
status_idx = np.random.choice(len(status), 15000, replace=True, p=weights)
status_b  = [Status[i] for i in status_idx)

生成加权重复列表
