• Last Updated : 26 Aug, 2019

Permutation.array_form() : array_form()
is a sympy Python library function that returns the 1 D copy of the argumeneted array.

Syntax : sympy.combinatorics.permutations.Permutation.array_form()

Return : copy of the Permutation in argument.

Code #1 : array_form() Example

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

Output :

Permutation a – array form : [2, 3, 0, 1]
Permutation b – array form : [1, 3, 5, 4, 2, 0]

Code #2 : array_form() Example – 2D Permutation

 `# Python code explaining``# SymPy.array_form()`` ` `# importing SymPy libraries``from` `sympy.combinatorics.partitions ``import` `Partition``from` `sympy.combinatorics.permutations ``import` `Permutation`` ` `# Using from sympy.combinatorics.permutations.Permutation.array_form() method `` ` `# creating Permutation``a ``=` `Permutation([[``2``, ``4``, ``0``], ``                 ``[``3``, ``1``, ``2``],``                 ``[``1``, ``5``, ``6``]])`` ` ` ` `print` `(``"Permutation a - array form : "``, a.array_form)`

Output :

Permutation a – array form : [3, 2, 4, 5, 0, 6, 1]
