Python Sympy Subset.next_lexicographic()用法及代码示例

Subset.next_lexicographic()：next_lexicographic()是一个sympy Python库函数，它返回下一个按字典顺序排序的子集。

用法：

sympy.combinatorics.subset.Subset.next_lexicographic()

返回：
下一个按字典顺序排序的子集

代码1：next_lexicographic()示例

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

输出：

Subset a next_lexicographic : [‘d’]

代码2：next_lexicographic()示例

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

输出：

Subset a next_lexicographic : [‘a’]
