  # Python | Sympy Permutation (). Array_form method

Python Methods and Functions

Using the `sympy.combinatorics.Permutation().array_form ` method, we can get a linear array from a multidimensional array or matrix using ` sympy.combinatorics.Permutation ( ) .array_form `.

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

Return: Return an array having single dimension.

Example # 1:
In this example, we see that with using ` sympy.combinatorics.Permutation (). array_form ` we can get a linear array from a matrix or multidimensional array.

` `

 ` # import sympy and permutation ` ` from ` ` sympy.combinatorics.permutations ` ` import ` ` Permutation ` ` from ` ` sympy ` ` import ` ` * `    ` Permutation.print_cyclic ` ` = ` ` False `   ` # Usage sympy.combinatorics.partitions.Permutation (). Array_form method ` ` gfg ` ` = ` ` Permutation ([ [` ` 1 ` `, ` ` 2 ` `, ` ` 3 ` `], [` ` 21 ` `, ` ` 32 ` `, ` ` 44 ` `]]) `   ` print ` ` (gfg.array_form) `

` `

Output:

[0, 2, 3, 1, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 32, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 44, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 21]

Example # 2:

 ` # import sympy and swap ` ` from ` ` sympy.combinatorics.permutations ` ` import ` ` Permutation ` ` from ` ` sympy ` ` import ` ` * `    ` Permutation.print_cyclic ` ` = ` ` False `   ` # Using sympy.combinatorics.partitions.Permutation (). Array_form method ` ` gfg ` ` = ` ` Permutation ([ [` ` 1 ` `, ` ` 2 ` `], [` ` 3 ` `, ` ` 4 ` `], [` ` 5 ` `]]) `   ` print ` ` (gfg.array_form) `

Output:

[0, 2, 1, 4, 3, 5]
