Last Updated : 26 Aug, 2019

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

Syntax :
sympy.combinatorics.Prufer.prufer.size()
Return :
size of the Prufer sequence

Code #1 : size() 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.size)

Output :

Prufer a size : 125

Code #2 : size() 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.size)

Output :

Prufer b size : 262144
