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