Python Sympy Permutation.support()用法及代碼示例

Permutation.support()：support()是一個sympy Python庫函數，它返回排列P中的元素，為此，P [i]!= i。

用法： sympy.combinatorics.permutations.Permutation.support()

返回：排列P中的元素，其中P [i]!= i。

代碼1：support()示例

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

輸出：

Permutation a – support form : [0, 1, 2, 3]
Permutation b – support form : [0, 1, 2, 3, 4, 5]

代碼2：support()示例

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

輸出：

Permutation a – support form : [0, 1, 2, 3, 4, 5, 6]
