Permutation.get_adjacency_distance() : get_adjacency_distance() is a sympy Python library function that calculates the adjacency distance between two permutations.

Syntax :

Return :

 `# Python code explaining``# SymPy.Permutation.get_adjacency_distance()`` ` `# importing SymPy libraries``from` `sympy.combinatorics.partitions ``import` `Partition``from` `sympy.combinatorics.permutations ``import` `Permutation`` ` `# Using from ``# sympy.combinatorics.permutations.Permutation.get_adjacency_distance() method `` ` `# creating Permutation``a ``=` `Permutation([``2``, ``0``, ``3``, ``1``, ``5``, ``4``])`` ` `b ``=` `Permutation([``3``, ``1``, ``2``, ``5``, ``4``, ``0``])`` ` `c ``=` `Permutation([``0``, ``1``, ``3``, ``4``, ``5``, ``2``])`` ` `print` `(``"a - get_adjacency_distance form b: "``, a.get_adjacency_distance(b))``print` `(``"b - get_adjacency_distance form c: "``, b.get_adjacency_distance(c))`

Output :

a – get_adjacency_distance form b: 3
b – get_adjacency_distance form c: 5
