Python SymPy Permutation.atoms()方法
Permutation.atoms() : atoms()是一个sympy Python库函数,它返回所有存在于permutation中的元素。
语法 : sympy.combinatorics.permutations.Permutation.atoms()
返回:论证的排列组合的元素。
代码 #1 : atoms() 示例
# Python code explaining
# SymPy.Permutation.atoms()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.atoms() method
# creating Permutation
a = Permutation([[2, 0], [3, 1]])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - atoms form : ", a.atoms())
print ("Permutation b - atoms form : ", b.atoms())
输出 :
Permutation a – atoms form : {0, 1, 2, 3}
Permutation b – atoms form : {0, 1, 2, 3, 4, 5}
代码#2:atoms()实例–二维排布
# Python code explaining
# SymPy.Permutation.atoms()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.atoms() method
# creating Permutation
a = Permutation([[2, 4, 0],
[3, 1, 2],
[1, 5, 6]])
print ("Permutation a - atoms form : ", a.atoms())
输出 :
Permutation a – ascents form : [1, 2, 4]
