Python 中的 SymPy | arrange.runs()
arrange.runs():runs()是一个 sympy Python 库函数，返回排列的游程。
游程=排列中的升序序列
语法:sympy.combinations .排列.置换. runs()
返回:排列的运行。
代码#1:运行()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:
排列 a–游程形式:[[2，3]，[0，1]] 排列 b–游程形式:[[1，3，5]，[4]，[2]，[0]]
代码#2:运行()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:
排列 a–运行形式:[[3]，[2，4，5]，[0，6]，[1]]
