I have a pandas dataframe like this:
ID Value
0 a 2
1 a 4
2 b 6
3 c 8
4 c 10
5 c 12
I would like to sample equally from the ID
groups. I know I can group the data frame by ID and then specify the number of rows I want to sample from each group like this:
df.groupby("ID").sample(n=2, replace = True)
However, I just want the probability of sampling from a group to be the same, not necessarily the exact same number of rows.
Thanks in advance.
