Python | SymPy Permutation.array_form() method

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]
