Prufer.prufer_repr() : prufer_repr() is a sympy Python library function that returns the Prufer sequence for the Prufer object. By removing the highest numbered vertex, then recording the node it was attached to, and finally continuing until only two vertices remain, the sequence can be found.

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

Return :
Prufer sequence for the Prufer object

Code #1 : prufer_repr() Example




# Python code explaining
# SymPy.Prufer.prufer_repr()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer
  
# Using from 
# sympy.combinatorics.prufer.Prufer.prufer_repr()
  
# Creating Prufer
a = Prufer([1, 2, 3], [2, 4, 5])
  
# prufer_repr value
print ("Prufer a prufer_repr : ", a.prufer_repr)


Output :

Prufer a prufer_repr : [1, 2, 3]

Code #2 : prufer_repr() Example




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


Output :

Prufer b prufer_repr : [1, 2, 3, 2, 4, 5]
