Randomly Sample Pyspark dataframe with column conditions

I'm trying to randomly sample a Pyspark dataframe where a column value meets a certain condition. I would like to use the sample method to randomly select rows based on a column value. Let's say I have the following data frame:

+---+----+------+-------------+------+
| id|code|   amt|flag_outliers|result|
+---+----+------+-------------+------+
|  1|   a|  10.9|            0|   0.0|
|  2|   b|  20.7|            0|   0.0|
|  3|   c|  30.4|            0|   1.0|
|  4|   d| 40.98|            0|   1.0|
|  5|   e| 50.21|            0|   2.0|
|  6|   f|  60.7|            0|   2.0|
|  7|   g|  70.8|            0|   2.0|
|  8|   h| 80.43|            0|   3.0|
|  9|   i| 90.12|            0|   3.0|
| 10|   j|100.65|            0|   3.0|
+---+----+------+-------------+------+

I would like to sample only 1(or any certain amount) of each of the 0, 1, 2, 3 based on the result column so I'd end up with this:

+---+----+------+-------------+------+
| id|code|   amt|flag_outliers|result|
+---+----+------+-------------+------+
|  1|   a|  10.9|            0|   0.0|
|  3|   c|  30.4|            0|   1.0|
|  5|   e| 50.21|            0|   2.0|
|  8|   h| 80.43|            0|   3.0|
+---+----+------+-------------+------+

Is there a good programmatic way to achieve this, i.e take the same number of rows for each of the values given in a certain column? Any help is really appreciated!
