Python SymPy Permutation.array_form()用法及代碼示例

Permutation.array_form()：array_form()是一個sympy Python庫函數，該函數返回argumeneted數組的一維副本。

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

返回：參數中Permutation的副本。

代碼1：array_form()示例

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

輸出：

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

代碼2：array_form()示例– 2D排列

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

輸出：

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