# SymPy | Prufer.tree_repr() in Python

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]]
