Python| SymPy Permutation.array_form() 方法

Permutation.array_form() ：array_form()是一个 sympy Python库函数，它返回参数化数组的一维副本。

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

Return : copy of the Permutation in argument.

代码 #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)

输出 ：

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

代码 #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)

输出 ：

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