原文:https://www.geesforgeks.org/sympy-subset-subset-in-python/
Subset.subset() : subset() 是一个 sympy Python 库函数，返回当前实例表示的子集。
语法: sympy.combinations.subset.subset.subset()
返回: 当前实例所代表的子集。
代码#1:子集()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:
子集 a 子集:['c '，' d']
代码#2:子集()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:
子集 a 子集:[2，3，4]
