SymPy | Permutation.runs() in Python
Permutation.runs() : runs() is a sympy Python library function that returns the runs of the permutation.
Runs = An ascending sequence in a permutation
Syntax : sympy.combinatorics.permutations.Permutation.runs()
Return : runs of the permutation.
Code #1 : runs() Example
# Python code explaining# SymPy.Permutation.runs() # importing SymPy librariesfrom sympy.combinatorics.partitions import Partitionfrom sympy.combinatorics.permutations import Permutation # Using from sympy.combinatorics.permutations.Permutation.runs() method # creating Permutationa = Permutation([[2, 0], [3, 1]]) b = Permutation([1, 3, 5, 4, 2, 0]) print ("Permutation a - runs form : ", a.runs())print ("Permutation b - runs form : ", b.runs()) |
Output :
Permutation a – runs form : [[2, 3], [0, 1]]
Permutation b – runs form : [[1, 3, 5], [4], [2], [0]]
Code #2 : runs() Example
# Python code explaining# SymPy.Permutation.runs() # importing SymPy librariesfrom sympy.combinatorics.partitions import Partitionfrom sympy.combinatorics.permutations import Permutation # Using from # sympy.combinatorics.permutations.Permutation.runs() method # creating Permutationa = Permutation([[2, 4, 0], [3, 1, 2], [1, 5, 6]]) print ("Permutation a - runs form : ", a.runs()) |
Output :
Permutation a – runs form : [[3], [2, 4, 5], [0, 6], [1]]
