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]
