语法: sympy.combinations.subset.subset.unlank_binary()
返回: 指定秩的二进制有序子集。
代码# 1:unlank_binary()示例
# Python code explaining
# SymPy.Subset.unrank_binary()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.unrank_binary()
# Creating Subset
a = Subset.unrank_binary(4, (['geek', 'for', 'c', 'd']))
# unrank_binary value
print ("Subset a unrank_binary : ", a.subset)
输出:
子集 a unlank_binary:[' for ']
