代码#1 : rmul_with_af()示例
# Python code explaining
# SymPy.Permutation.rmul_with_af()
# importing SymPy libraries
from sympy.combinatorics.partitions import Partition
from sympy.combinatorics.permutations import Permutation
# Using from sympy.combinatorics.permutations.Permutation.rmul_with_af() method
# creating Permutation
a = Permutation([[2, 0], [3, 1]])
b = Permutation([1, 3, 5, 4, 2, 0])
print ("Permutation a - rmul_with_af form : ", a.rmul_with_af(b))
print ("Permutation b - rmul_with_af form : ", b.rmul_with_af(a))
输出:
排列 a–rmul _ with _ af 形式:(0 1 3 4 2 5) 排列 b–rmul _ with _ af 形式:(0 2)(1 3)
