Permutation.length() : length() is a sympy Python library function that finds the number of integers moved by the permutation.
Syntax : sympy.combinatorics.permutations.Permutation.length()
Return : number of integers moved by the permutation
Code #1 : length() Example
# Python code explaining # SymPy.Permutation.length() # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation # Using from sympy.combinatorics.permutations.Permutation.length() method # creating Permutation a = Permutation([[ 2 , 0 ], [ 3 , 1 ]]) b = Permutation([ 1 , 3 , 5 , 4 , 2 , 0 ]) print ( "Permutation a - length form : " , a.length()) print ( "Permutation b - length form : " , b.length()) |
Output :
Permutation a – length form : 4
Permutation b – length form : 6
Code #2 : length() Example – 2D Permutation
# Python code explaining # SymPy.Permutation.length() # importing SymPy libraries from sympy.combinatorics.partitions import Partition from sympy.combinatorics.permutations import Permutation # Using from sympy.combinatorics.permutations.Permutation.length() method # creating Permutation a = Permutation([[ 2 , 4 , 0 ], [ 3 , 1 , 2 ], [ 1 , 5 , 6 ]]) print ( "Permutation a - length form : " , a.length()) |
Output :
Permutation a – length form : 7
