Let L = [0,1,1,2,2,2,2,]. I want to generate all the multi-partitions of L in which each part can have repeated entries and the parts themselves can repeat in the partition.

For example, [[0],[1,2],[1,2],[2,2]] is one such partition of L.

Kindly help me with this. Thank you.

Generate partitions of list(range(len(L))) and apply $k \mapsto L[k]$ to each element in each part?
