SymPy | Prufer.to_tree() in Python

Prufer.to_tree() : to_tree() is a sympy Python library function that returns the tree representation of the Prufer sequence.

Syntax :
sympy.combinatorics.Prufer.prufer.to_tree()

Return :
representation of the Prufer sequence

Code #1 : to_tree() Example

# Python code explaining
# SymPy.Prufer.to_tree()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer

# Using from
# sympy.combinatorics.prufer.Prufer.to_tree()

# Creating Prufer
a = Prufer([1, 2, 3], [2, 4, 5], 4)

# to_tree value
print ("Prufer a to_tree : ", Prufer.to_tree([0, 2]))

Output :

Prufer a to_tree : [[0, 1], [0, 2], [2, 3]]

Code #2 : to_tree() Example

# Python code explaining
# SymPy.Prufer.to_tree()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer

# Using from
# sympy.combinatorics.prufer.Prufer.to_tree()

# Creating Prufer
b = Prufer([1, 2, 3, 2, 4, 5], [6, 7], [8], 4)

# to_tree value
print ("Prufer b to_tree : ", Prufer.to_tree([0, 2]))

Output :

Prufer b to_tree : [[0, 1], [0, 2], [2, 3]]
