subset.rank_Gray():rank_Gray()是一个 sympy Python 库函数，返回子集的格雷码排名。
语法: sympy.combinations.subset.subset.rank_gray()
返回: 子集的格雷码排名
代码#1 : rank_gray()示例
# Python code explaining
# SymPy.Subset.rank_gray()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.rank_gray()
# Creating Subset
a = Subset(['c', 'd'], ['geek', 'for', 'c', 'd'])
# rank_gray value
print ("Subset a rank_gray : ", a.rank_gray)
输出:
子集 a 等级_灰色:2
代码#2 : rank_gray()示例
# Python code explaining
# SymPy.Subset.rank_gray()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.rank_gray()
# Creating Subset
a = Subset([2, 3, 4], [1, 2, 3, 4, 5])
# rank_gray value
print ("Subset a rank_gray : ", a.rank_gray)
输出:
子集 a 等级_灰色:11
