Prufer.rank() : rank() is a sympy Python library function that returns the rank of the Prufer sequence.
Syntax :
sympy.combinatorics.Prufer.prufer.rank()Return :
rank of the Prufer sequence
Code #1 : rank() Example
# Python code explaining # SymPy.Prufer.rank() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.prufer import Prufer # Using from # sympy.combinatorics.prufer.Prufer.rank() # Creating Prufer a = Prufer([1, 2, 3], [2, 4, 5]) # rank value print ("Prufer a rank : ", a.rank) |
Output :
Prufer a rank : 38
Code #2 : rank() Example
# Python code explaining # SymPy.Prufer.rank() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.prufer import Prufer # Using from # sympy.combinatorics.prufer.Prufer.rank() # Creating Prufer b = Prufer([1, 2, 3, 2, 4, 5], [6, 7], [8]) # rank value print ("Prufer b rank : ", b.rank) |
Output :
Prufer b rank : 42661
