I have a dataframe (pandas python) in this format:
| ID | Valor |
|---|---|
| 1 | 15 |
| 1 | 10 |
| 1 | 25 |
| 2 | 13 |
| 3 | 10 |
| 3 | 11 |
What I want to do is join the data by id into a list so that it looks like this:
| ID | Valor |
|---|---|
| 1 | [15,10,25] |
| 2 | 13 |
| 3 | [10,11] |
Someone can help me, please?

Use:
df2 = df.groupby('ID', as_index = False)['Valor'].agg(list)
