# SymPy | Prufer.size() in Python

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
