Python | SymPy Permutation.array_form() method
  • Last Updated : 26 Aug, 2019


Permutation.array_form() : array_form()
is a sympy Python library function that returns the 1 D copy of the argumeneted array.

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

Return : copy of the Permutation in argument.

Code #1 : array_form() Example




# 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




# 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]
