Python 中的 SymPy | arrange . size()
原文:https://www . geesforgeks . org/sympy-排列-python 中的大小/
arrange . size():size()是一个 sympy Python 库函数，返回排列中的元素个数。
语法:sympy . combinations .排列.置换. size()
返回:排列中的元素个数。
代码#1:大小()示例
# Python code explaining
# SymPy.Permutation.size()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from
# sympy.combinatorics.permutations.Permutation.size() method
# creating Permutation
a = Permutation([[2, 0], [3, 1]])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - size form : ", a.size)
print ("Permutation b - size form : ", b.size)
输出:
排列 a–大小形式:4
排列 b–大小形式:6
代码#2:大小()示例
# Python code explaining
# SymPy.Permutation.size()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from
# sympy.combinatorics.permutations.Permutation.size() method
# creating Permutation
a = Permutation([[2, 4, 0],
[3, 1, 2],
[1, 5, 6]])
print ("Permutation a - size form : ", a.size)
输出:
排列 a-大小形式:7
