Hi,
I am relatively new to sympy but like it and try to use it for my
calculations.
Now, I would like to use symbolic terms for further numeric
calculations.
I tried to use something like .subs(x,range(20)) but it did not work.
Is there a way to treat symbols in a symbolic expression like a list
o
Maybe we should vectorize subs, but in the meanwhile, you can use list
comprenehsions, and map if you want to evalf:
In [5]: s = x*pi
In [6]: [s.subs(x, i) for i in range(10)]
Out[6]: [0, π, 2⋅π, 3⋅π, 4⋅π, 5⋅π, 6⋅π, 7⋅π, 8⋅π, 9⋅π]
In [7]: map(N, [s.subs(x, i) for i in range(10)])
Out[7]: [0, 3.
I also made this issue for this:

What do you think about a subs function? I just realized that would have to be
a lambda for map anyway because it takes multiple arguments. So I could go
either way on that.
