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
