Python SymPy Permutation.array_form()方法

Permutation.array_form() : array_form() 是一个Sympy Python库函数，用于返回参数数组的1 D副本。

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

返回：参数中Permutation的副本。

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() 例子 – 二维排列组合

# 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]
