# SymPy | Permutation.list() in Python

Permutation.list() : list() is a sympy Python library function that returns the permutation as an explicit list, possibly trimming unmoved elements if size is less than the maximum element in the permutation.

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

Return : permutation as an explicit list

Code #1 : list() Example

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

Output :

Permutation a – list form : [2, 3, 0, 1]
Permutation b – list form : [1, 3, 5, 4, 2, 0]

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

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

Output :

Permutation a – list form : [3, 2, 4, 5, 0, 6, 1]
