507exposes it to Python. Besides the relative flexibility of the implementation,
508it also scales well, and can be run on graphs of millions of nodes (as long as
509they can fit in memory). The core function is @code{find_partition} which
510finds the optimal partition using the Leiden algorithm, which is an extension
511of the Louvain algorithm, for a number of different methods.")
