I recommend using pyparsing or similar parser to parse it; if merely to ensure that it's a valid algorithim.

Subject: [Tutor] avoid eval how???

Hello

 

I have a dynamic functions which created by some algorithms during runtime.

These functions are in string type.

When I want to use it, I can use eval command.

But can someone give me more suggestion about how to handle this problem, I want to avoid eval.

 

Example :

L = ['x+sin(x)', '1/(2.2 + pow(2,3)/sin(30)']

 

 

Sincerely Yours,

pujo
