Python | SymPy placement .换向器()方法
arrange .换向器() :换向器()是一个 sympy Python 库函数，返回分区的换向器。假设‘a’和‘b’是‘C’的一部分，那么 a 和 b 的换向器就是‘C’的同一性如果 a 和 b 通勤，即 ab == ba。
语法: sympy.combinations .排列.置换.换向器()
返回:分区的 换向器
代码#1:换向器()示例
# Python code explaining
# SymPy.Permutation.commutator()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.commutator() method
# creating Permutation
a = Permutation([2, 0, 3, 1, 5, 4])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - commutator form : ", a.commutator(b))
print ("Permutation b - commutator form : ", b.commutator(a))
输出:
置换 a–换向形式:置换([3，1，2，5，4，0]) 置换 b–换向形式:置换([5，1，2，0，4，3])
代码#2:换向器()示例–自换向器
# Python code explaining
# SymPy.Permutation.commutator()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.commutator() method
# creating Permutation
a = Permutation([[2, 4, 0],
[3, 1, 2],
[1, 5, 6]])
# SELF COMMUTATING
print ("Permutation a - commutator form : ", a.commutator(a))
输出:
置换 a–换向器形式:置换([]，大小=7)
