它的工作原理就像一个Python。您可以将其转换为列表并通过索引提取元素,例如:FiniteSetset
In [3]: S = FiniteSet(7335.64225447845*exp(-1.77553477605362*sqrt(2)))
In [4]: S
Out[4]:
⎧ -1.77553477605362⋅√2⎫
⎨7335.64225447845⋅ℯ ⎬
⎩ ⎭
In [5]: list(S)
Out[5]:
⎡ -1.77553477605362⋅√2⎤
⎣7335.64225447845⋅ℯ ⎦
In [6]: list(S)[0]
Out[6]:
-1.77553477605362⋅√2
7335.64225447845⋅ℯ
In [7]: list(S)[0].n()
Out[7]: 595.567591563886
