Python Sympy Permutation.size()用法及代码示例

Permutation.size()：size()是一个sympy Python库函数，它返回排列中的元素数。

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

返回：排列中元素的数量。

代码1：size()示例

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

输出：

Permutation a – size form : 4
Permutation b – size form : 6

代码2：size()示例

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

输出：

Permutation a – size form : 7
