a simple code :
import sympy as sp sp.var('a b c',nonzero=True) eq = Eq(a*b,a*c) display(eq) display(eq.simplify()) Both display exhibit : ab = ac I would have liked sympy to simply remove 'a', which is possible because I mentioned 'a' is nonzero. What's wrong ? Best regards, Mike -- You received this message because you are subscribed to the Google Groups "sympy" group.
