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]
