trees_have_same_structure

t3toolbox.backend.stacking.trees_have_same_structure(tree1, tree2)

def trees_have_same_structure(
        tree1,  # nested tuples of leaves (the structure to check)
        tree2,  # nested tuples of leaves (the structure to check against)
) -> bool:      # True iff tree1 and tree2 have identical nesting structure

Checks if two trees (nested sequences) have the same structure.

Examples

>>> import numpy as np
>>> import t3toolbox.backend.stacking as stacking
>>> T = ((1, (2,3)),4,(5,6,7))
>>> LS = ((None, (None, None)), None, (None, None, None))
>>> stacking.trees_have_same_structure(T, LS)
True

>>> import numpy as np
>>> import t3toolbox.backend.stacking as stacking
>>> T = ((1, (2,3)),4,(5,6,7))
>>> LS = ((None, (None)), None, (None, None, None))
>>> stacking.trees_have_same_structure(T, LS)
False

>>> import numpy as np
>>> import t3toolbox.backend.stacking as stacking
>>> T = ((1, (2,3)),4,(5,6,7), ())

>>> T = (T1, T2)
>>> LS = ((None, (None, None)), None, (None, None, None))
>>> stacking.trees_have_same_structure(T, LS)
False
