Python 中的 SymPy | Subset.size()
原文:https://www.geeksforgeeks.org/sympy-subset-size-in-python/
Subset.size() : size() 是一个 sympy Python 库函数，返回子集的大小。
语法: sympy.combinations.subset.subset.size()
返回: 子集的大小。
代码#1:大小()示例
# Python code explaining
# SymPy.Subset.size()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.size()
# Creating Subset
a = Subset(['c', 'd'], ['geek', 'for', 'c', 'd'])
# size value
print ("Subset a size : ", a.size)
输出:
子集 a 大小:2
代码#2:大小()示例
# Python code explaining
# SymPy.Subset.size()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.subsets import Subset
# Using from
# sympy.combinatorics.subset.Subsets.size()
# Creating Subset
a = Subset([2, 3, 4], [1, 2, 3, 4, 5])
# size value
print ("Subset a size : ", a.size)
输出:
子集 a 大小:3
