# SymPy | Permutation.random() in Python

Permutation.random() : random() is a sympy Python library function that returns the random permutation of length ‘n’.

Syntax : sympy.combinatorics.permutations.Permutation.random()

Return : random permutation of length

Code #1 : random() Example

 `# Python code explaining ` `# SymPy.Permutation.random() ` ` `  `# importing SymPy libraries ` `from` `sympy.combinatorics.partitions ``import` `Partition ` `from` `sympy.combinatorics.permutations ``import` `Permutation ` ` `  `# Using from sympy.combinatorics.permutations.Permutation.random() method  ` ` `  `# creating Permutation ` `a ``=` `Permutation([[``2``, ``0``], [``3``, ``1``]]) ` ` `  `b ``=` `Permutation([``1``, ``3``, ``5``, ``4``, ``2``, ``0``]) ` ` `  ` `  `print` `(``"Permutation a - random form : "``, a.random(``2``)) ` `print` `(``"Permutation b - random form : "``, b.random(``5``)) `

Output :

Permutation a – random form : (1)
Permutation b – random form : (4)

Code #2 : random() Example – 2D Permutation

 `# Python code explaining ` `# SymPy.Permutation.random() ` ` `  `# importing SymPy libraries ` `from` `sympy.combinatorics.partitions ``import` `Partition ` `from` `sympy.combinatorics.permutations ``import` `Permutation ` ` `  `# Using from  ` `# sympy.combinatorics.permutations.Permutation.random() method  ` ` `  `# creating Permutation ` `a ``=` `Permutation([[``2``, ``4``, ``0``],  ` `                 ``[``3``, ``1``, ``2``], ` `                 ``[``1``, ``5``, ``6``]]) ` ` `  ` `  `print` `(``"Permutation a - random form : "``, a.random(``4``)) `

Output :

Permutation a – random form : (0 1 2 3)
