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.
Here’s a quick example:
>>> tree.map_structure(lambda v: v**2, [, [[[2, 3]]], ]) [, [[[4, 9]]], ]
tree has originally been part of TensorFlow and is available
tree by running:
$ pip install dm-tree
