Python Sympy Subset.ksubsets()用法及代码示例


Subset.ksubsets():ksubsets()是一个sympy Python库函数,按字典顺序返回大小为k的子集。

用法:
sympy.combinatorics.subset.Subset.ksubsets()

返回:
按字典顺序排列的大小为k的子集。


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:

Subset 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:

Subset a ksubsets : [2, 3]
