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

Permutation.runs()：runs()是一个sympy Python库函数，它返回排列的运行。

游程=排列中的升序

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

返回：排列的运行。

代码1：runs()示例

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

输出：

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

代码2：runs()示例

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

输出：

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