SymPy | Python中的 Subset.next_gray()

Subset.next_gray() ：next_gray()是一个 sympy Python库函数，它返回下一个格雷码有序子集。

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

Return :
the next Gray code ordered subset

代码 #1：next_gray() 示例

# Python code explaining
# SymPy.Subset.next_gray()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.next_gray()
  
# Creating Subset
a = Subset(['c', 'd'], ['geek', 'for', 'c', 'd'])
  
# next_gray value
print ("Subset a next_gray : ", a.next_gray().subset)

输出 ：

Subset a next_gray : [‘c’]

代码 #2：next_gray() 示例

# Python code explaining
# SymPy.Subset.next_gray()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.next_gray()
  
# Creating Subset
a = Subset(['k', 'd'], ['23', 'k', 'd'])
  
# next_gray value
print ("Subset a next_gray : ", a.next_gray().subset)

输出 ：

Subset a next_gray : [‘k’]
