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

# 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]
