Python 中的 SymPy | arrange.support()
replacement.support():support()是一个 sympy Python 库函数，返回 replacement 中的元素，P，为此 P[i]！= i。
语法:sympy.combinations .排列.置换. support()
返回:排列中的元素，P，为哪个 P[i]！= i。
代码#1:支持()示例
# Python code explaining
# SymPy.Permutation.support()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.support() method
# creating Permutation
a = Permutation([[2, 0], [3, 1]])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - support form : ", a.support())
print ("Permutation b - support form : ", b.support())
输出:
排列 a–支持形式:[0，1，2，3] 排列 b–支持形式:[0，1，2，3，4，5]
