# Tree
|
|
|
|
`tree` is a library for working with nested data structures. In a way, `tree`
|
|
generalizes the builtin `map` function which only supports flat sequences,
|
|
and allows to apply a function to each "leaf" preserving the overall
|
|
structure.
|
|
|
|
```python
|
|
>>> import tree
|
|
>>> structure = [[1], [[[2, 3]]], [4]]
|
|
>>> tree.flatten(structure)
|
|
[1, 2, 3, 4]
|
|
>>> tree.map_structure(lambda v: v**2, structure)
|
|
[[1], [[[4, 9]]], [16]]
|
|
```
|
|
|
|
`tree` is backed by an optimized C++ implementation suitable for use in
|
|
demanding applications, such as machine learning models.
