pyarrow.compute.list_flatten#
- pyarrow.compute.list_flatten(lists, /, recursive=False, *, options=None, memory_pool=None)#
Flatten list values.
lists must have a list-like type (lists, list-views, and fixed-size lists). Return an array with the top list level flattened unless recursive is set to true in ListFlattenOptions. When that is that case, flattening happens recursively until a non-list array is formed.
Null list values do not emit anything to the output.
- Parameters:
- listsArray-like
Argument to compute function.
- recursivebool, default
False When True, the list array is flattened recursively until an array of non-list values is formed.
- options
pyarrow.compute.ListFlattenOptions, optional Alternative way of passing options.
- memory_pool
pyarrow.MemoryPool, optional If not passed, will allocate memory from the default memory pool.
