SymPy | Subset.unrank_gray() in Python

Subset.unrank_gray() : unrank_gray() is a sympy Python library function that returns the Gray code ordered subset of the specified rank.

Syntax :
sympy.combinatorics.subset.Subset.unrank_gray()

Return :
the Gray code ordered subset of the specified rank.

Code #1 : unrank_gray() Example

# Python code explaining
# SymPy.Subset.unrank_gray()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset

# Using from
# sympy.combinatorics.subset.Subsets.unrank_gray()

# Creating Subset
a = Subset.unrank_gray(4, (['geek', 'for', 'c', 'd']))

# unrank_gray value
print ("Subset a unrank_gray : ", a.subset)

Output :

Subset a unrank_gray : [‘for’, ‘c’]

Code #2 : unrank_gray() Example

# Python code explaining
# SymPy.Subset.unrank_gray()

# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset

# Using from
# sympy.combinatorics.subset.Subsets.unrank_gray()

# Creating Subset
a = Subset.unrank_gray(4, ([2, 3, 4]))

# unrank_gray value
print ("Subset a unrank_gray : ", a.subset)

Output :

Subset a unrank_gray : [2, 3]
