SymPy | Permutation.size() in Python

Last Updated : 27 Aug, 2019

Permutation.size() : size() is a sympy Python library function that returns the number of elements in the permutation.

Syntax : sympy.combinatorics.permutations.Permutation.size() Return : number of elements in the permutation.

Code #1 : size() Example

Python3 1=1

# Python code explaining
# SymPy.Permutation.size()

# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation

# Using from 
# sympy.combinatorics.permutations.Permutation.size() method 

# creating Permutation
a = Permutation([[2, 0], [3, 1]])

b = Permutation([1, 3, 5, 4, 2, 0])


print ("Permutation a - size form : ", a.size)
print ("Permutation b - size form : ", b.size)

Output :

Permutation a - size form : 4 Permutation b - size form : 6

Code #2 : size() Example

Python3 1=1

# Python code explaining
# SymPy.Permutation.size()

# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation

# Using from 
# sympy.combinatorics.permutations.Permutation.size() method 

# creating Permutation
a = Permutation([[2, 4, 0], 
                 [3, 1, 2],
                 [1, 5, 6]])


print ("Permutation a - size form : ", a.size)

Output :

Permutation a - size form : 7
