replacement.cyclic_form():cyclic_form()是一个 sympy Python 库函数，通过省略单线态，从规范符号返回循环符号。
语法: 符号组合学.排列.置换.循环形式()
从规范符号返回: 循环符号
代码#1:循环形式()示例
# Python code explaining
# SymPy.Permutation.cyclic_form()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.cyclic_form() method
# creating Permutation
a = Permutation([2, 0, 3, 1, 5, 4])
b = Permutation([3, 1, 2, 5, 4, 0])
print ("Permutation a - cyclic_form form : ", a.cyclic_form)
print ("Permutation b - cyclic_form form : ", b.cyclic_form)
输出:
排列 a–循环形式:[[0，2，3，1]，[4，5]] 排列 b–循环形式:[[0，3，5]]
代码#2:循环形式()示例–2D 置换
# Python code explaining
# SymPy.Permutation.cyclic_form()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from
# sympy.combinatorics.permutations.Permutation.cyclic_form() method
# creating Permutation
a = Permutation([[2, 4, 0],
[3, 1, 2],
[1, 5, 6]])
# SELF COMMUTATING
print ("Permutation a - cyclic_form form : ", a.cyclic_form)
输出:
置换 a–循环形式形式:[[0，3，5，6，1，2，4]]
