Hello, I would like to use sympy in the following way : 1. The user types some formula like for example "2*x**3+5". 2. My little program named test.py must have to differentiate this formula.
The problem is that the formula is known as a string. Is there a way to not used string so as to work with the user's formula ? Best regards. Christophe. PS : I send this message because Ondrej said to not use string in some messages. -- You received this message because you are subscribed to the Google Groups "sympy" group.
