Python SymPy Permutation.cycles()用法及代码示例

Permutation.cycles()：cycles()是一个sympy Python库函数，它返回排列中存在的循环数。这也包括单例。

用法：

sympy.combinatorics.permutations.Permutation.cycles()

返回：
排列中存在的循环数

代码1：cycles()示例

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

输出：

Permutation a – cycles form : 2
Permutation b – cycles form : 4

代码2：cycles()示例– 2D排列

# Python code explaining 
# SymPy.Permutation.cycles() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from  
# sympy.combinatorics.permutations.Permutation.cycles() method  
  
# creating Permutation 
a = Permutation([[2, 4, 0],  
                 [3, 1, 2], 
                 [1, 5, 6]]) 
  
# SELF COMMUTATING     
print ("Permutation a - cycles form : ", a.cycles)

输出：

Permutation a – cycles form : 1
