代码 #1 : full_cyclic_form() 示例
# Python code explaining
# SymPy.Permutation.full_cyclic_form()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.full_cyclic_form() method
# creating Permutation
a = Permutation([2, 0, 3, 1, 5, 4])
b = Permutation([3, 1, 2, 5, 4, 0])
print ("Permutation a - full_cyclic_form form : ", a.full_cyclic_form)
print ("Permutation b - full_cyclic_form form : ", b.full_cyclic_form)
输出 :
Permutation a – full_cyclic_form form : [[0, 2, 3, 1], [4, 5]]
Permutation b – full_cyclic_form form : [[0, 3, 5], [1], [2], [4]]
