Note, the follow likely does not do what you expect: expr = sin(z*2*pi) z = 0 expr We’ve now redefined z to be a python type type(z) int to do substitution, we use the subs () method expr = sin(x*2*pi) expr a = expr.subs(x, 0.125) a

I don't see how it is any different from just oo." (Comment 18) Yes, roo is really different from oo. However, I'm not convinced it is currently useful. Since sympy works in the (extended) complex field, 1/0 must return zoo, not roo. In fact, I don't see for now any use for it in sympy. So, let's forget about it... flats at ponce market
