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