# Python | Sympy Permutation().array_form method

With the help of `sympy.combinatorics.Permutation().array_form` method, we can get the linear array from multidimensional array or matrix by using `sympy.combinatorics.Permutation().array_form` method.

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

Return : Return an array having single dimension.

Example #1 :
In this example we can see that by using `sympy.combinatorics.Permutation().array_form` method, we are able to get the linear array from matrix or multidimensional array.

 `# import sympy and Permutation ` `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``], [``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 Permutation ` `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]
