返回:
先前的格雷碼排序子集。


代碼1:prev_gray()示例

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

輸出:

Subset a prev_gray : [‘d’]

代碼2:prev_gray()示例

# Python code explaining 
# SymPy.Subset.prev_gray() 
  
# importing SymPy libraries 
from sympy.combinatorics import Permutation, Cycle 
from sympy.combinatorics.subsets import Subset 
  
# Using from  
# sympy.combinatorics.subset.Subsets.prev_gray() 
  
# Creating Subset 
a = Subset([2, 3, 4], [1, 2, 3, 4, 5]) 
  
# prev_gray value 
print ("Subset a prev_gray : ", a.prev_gray().subset)

輸出:

Subset a prev_gray : [2, 3, 4, 5]
