Prufer.tree_repr() : tree_repr() is a sympy Python library function that returns the tree representation of Prufer sequence.
Syntax : sympy.combinatorics.Prufer.prufer.tree_repr() Return : tree representation of Prufer sequence
Code #1 : tree_repr() Example
# Python code explaining
# SymPy.Prufer.tree_repr()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer
  
# Using from 
# sympy.combinatorics.prufer.Prufer.tree_repr()
  
# Creating Prufer
a = Prufer([1, 2, 3], [2, 4, 5])
  
# tree_repr value
# rank = 2
# n = 5
print ("Prufer a tree_repr : ", a.tree_repr)

                    
Output :
Prufer a tree_repr : [[0, 1], [1, 2], [2, 3], [3, 4]]
Code #2 : tree_repr() Example
# Python code explaining
# SymPy.Prufer.tree_repr()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer
  
# Using from 
# sympy.combinatorics.prufer.Prufer.tree_repr()
  
# Creating Prufer
b = Prufer([1, 2, 3, 2, 4, 5], [6, 7], [8])
  
# tree_repr value
# rank = 2
# n = 5
print ("Prufer b tree_repr : ", b.tree_repr)

                    
Output :
Prufer b tree_repr : [[0, 1], [1, 2], [3, 6], [2, 3], [2, 4], [4, 5], [5, 7]]
