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]
