Permutation.is_Identity() : is_Identity() is a sympy Python library function that checks whether the Permutation is an identity permutation.
Syntax : sympy.combinatorics.permutations.Permutation.is_Identity()
Return : true – if he Permutation is an identity permutation; otherwise false
Code #1 : is_Identity() Example
# Python code explaining # SymPy.Permutation.is_Identity() # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation # Using from sympy.combinatorics.permutations.Permutation.is_Identity() method # creating Permutation a = Permutation([[2, 0], [3, 1]]) b = Permutation([1, 3, 5, 4, 2, 0]) print ("Permutation a - is_Identity form : ", a.is_Identity) print ("Permutation b - is_Identity form : ", b.is_Identity) |
Output :
Permutation a – is_Identity form : False
Permutation b – is_Identity form : False
Code #2 : is_Identity() Example – 2D Permutation
# Python code explaining # SymPy.Permutation.is_Identity() # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation # Using from sympy.combinatorics.permutations.Permutation.is_Identity() method # creating Permutation a = Permutation([[2, 4, 0], [3, 1, 2], [1, 5, 6]]) print ("Permutation a - is_Identity form : ", a.is_Identity) |
Output :
Permutation a – is_Identity form : False
