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
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import 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
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import 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)
