Evaluate sympy expression from an array of values

Question

I\'m experimenting with sympy and I\'ve hit upon an issue I can\'t work out.

Using scipy I can write an expression and evaluate it for an array of x values as follow

Answer 1

While the accepted answer makes it clear that the OP was looking for numerical evaluation, I'll still point out that one can also have symbolic evaluation by using symarray:

import sympy
xs = sympy.symarray('x', 10)
f = lambda x: x**2
f(xs)

yields

array([x_0**2, x_1**2, x_2**2, x_3**2, x_4**2, x_5**2, x_6**2, x_7**2,
       x_8**2, x_9**2], dtype=object)

Note that this also uses a numpy array internally, but one filled with sympy.Expressions.
