Prufer.to_prufer() : to_prufer() is a sympy Python library function that returns the Prufer sequence for a argumented tree which is given as a list of edges and n is the number of nodes in the tree.
Syntax :
sympy.combinatorics.Prufer.prufer.to_prufer()Return :
Prufer sequence for a argumented tree
Code #1 : to_prufer() Example
# Python code explaining # SymPy.Prufer.size() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.prufer import Prufer # Using from # sympy.combinatorics.prufer.Prufer.size() # Creating Prufer a = Prufer([1, 2, 3], [2, 4, 5]) # size value print ("Prufer a size : ", a.to_prufer([[0, 1], [0, 2], [0, 3]], 4)) |
Output :
Prufer a size : [0, 0]
Code #2 : to_prufer() Example
# Python code explaining # SymPy.Prufer.size() # importing SymPy libraries from sympy.combinatorics import Permutation, Cycle from sympy.combinatorics.prufer import Prufer # Using from # sympy.combinatorics.prufer.Prufer.size() # Creating Prufer b = Prufer([1, 2, 3, 2, 4, 5], [6, 7], [8]) # size value print ("Prufer b size : ", b.to_prufer([[0, 1], [0, 2], [0, 3]], 4)) |
Output :
Prufer b size : [0, 0]
