Permutation.array_form() : array_form() is a sympy Python library function that returns the 1 D copy of the augmented array.
Syntax : sympy.combinatorics.permutations.Permutation.array_form() Return : copy of the Permutation in argument.
Code #1 : array_form() Example
Python3
# 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
Python3
# 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]
