the subset represented by the current instance.

代码 #1：subset() 示例

# Python code explaining
# SymPy.Subset.subset()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.subset()
  
# Creating Subset
a = Subset(['c', 'd'], ['geek', 'for', 'c', 'd'])
  
# subset value
print ("Subset a subset : ", a.subset)

输出 ：

Subset a subset : [‘c’, ‘d’]

代码 #2：subset() 示例

# Python code explaining
# SymPy.Subset.subset()
  
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
  
# Using from 
# sympy.combinatorics.subset.Subsets.subset()
  
# Creating Subset
a = Subset([2, 3, 4], [1, 2, 3, 4, 5])
  
# subset value
print ("Subset a subset : ", a.subset)

输出 ：

Subset a subset : [2, 3, 4]
