原文:https://www.geesforgeks.org/sympy-subset-next_gray-in-python/
subset.next_gray():next_Gray()是一个 sympy Python 库函数，返回下一个 Gray 码有序子集。
语法: sympy.combinations.subset.subset.next_gray()
返回: 下一个格雷码有序子集
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:
子集 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:
子集 a next_gray : ['k']
