subset.ksubsets():ksubsets()是一个 sympy Python 库函数，按照字典顺序返回大小为 k 的子集。
语法: sympy.combinations.subset.subset.ksubsets()
返回: 大小为 k 的子集按字典顺序排列。
代码#1 : ksubsets()示例
# Python code explaining
# SymPy.Subset.ksubsets()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.ksubsets()
# Creating Subset
a = Subset.ksubsets(4, (['geek', 'for', 'c', 'd']))
# ksubsets value
print ("Subset a ksubsets : ", a.subset)
输出:
子集 a ksubsets : ['for '，' c']
代码#2 : ksubsets()示例
# Python code explaining
# SymPy.Subset.ksubsets()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.ksubsets()
# Creating Subset
a = Subset.ksubsets(4, ([2, 3, 4]))
# ksubsets value
print ("Subset a ksubsets : ", a.subset)
输出:
