SymPy | Python中的 Permutation.min()

Permutation.min() : min()是一个 sympy Python库函数，它返回排列中的最小值。

Syntax : sympy.combinatorics.permutations.Permutation.min()

Return : minimum value in the permutation

代码 #1：min() 示例

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

输出 ：

Permutation a – min form : 0
Permutation b – min form : 0

from sympy.combinatorics.permutations import Permutation
  
# Using from sympy.combinatorics.permutations.Permutation.min() method 
  
# creating Permutation
a = Permutation([[2, 4, 0], 
                 [3, 1, 2],
                 [1, 5, 6]])
  
  
print ("Permutation a - min form : ", a.min())

输出 ：

Permutation a – min form : 0
