I have the following pandas.DataFrame

   match_id  court
0  50311513      1
1  50313011      2
2  50313009      2
3  50317691      1
4  50315247      2
5  50318597      1
6  50318877      1
7  50318983      1
8  50318831      1
9  50318595      1

As you can see there are a total of 2 courses. I want to bundle each “slot” together.
So, the first grouped df should contain match 50311513 and 50313011. The second slot should contain 50313009 and 50317691. After the third slot, the grouped df is basically a single row.

How can I tell pandas.groupby() that only one match can be played on the course?

Thanks
