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

Permutation.cardinality()：cardinality()是一個sympy Python庫函數，它返回所有可能的排列數。

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

返回：所有可能的排列數

代碼1：cardinality()示例

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

輸出：

Permutation a – cardinality form : 24
Permutation b – cardinality form : 720

代碼2：cardinality()示例– 2D排列

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

輸出：

Permutation a – cardinality form : 5040
