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

Permutation.get_positional_distance()：get_positional_distance()是一個sympy Python庫函數，用於計算兩個置換之間的位置距離。

用法：

sympy.combinatorics.permutations.Permutation.get_positional_distance()

返回：
兩個排列之間的位置距離

代碼1：get_positional_distance()示例

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

輸出：

a – get_positional_distance form b: 12
b – get_positional_distance form c: 8

代碼2：get_positional_distance()示例– 2D排列

# Python code explaining 
# SymPy.Permutation.get_positional_distance() 
  
# importing SymPy libraries 
from sympy.combinatorics.partitions import Partition 
from sympy.combinatorics.permutations import Permutation 
  
# Using from  
# sympy.combinatorics.permutations.Permutation.get_positional_distance() method  
  
# creating Permutation 
a = Permutation([[2, 4, 0],  
                 [7, 1, 3], 
                 [8, 5, 6]]) 
  
b = Permutation([[8, 4, 0],  
                 [2, 7, 0], 
                 [1, 6, 7]]) 
      
print ("a get_positional_distance form b : ", a.get_positional_distance(b))

輸出：

a get_positional_distance form b : 22
