Here's my problem, and hopefully someone can help me figure out if there is
a good way to do this.
I am writing a program that allows the user to enter an equation in a text
field using pre-existing variables. They then enter numerical values for
these variables, or can tell the program to randomize the values used within
a certain bounds. My problem is taking in this equation they have written
in the text field and converting it into an equation Python can calculate.
The only way I know of to do this is by parsing it, which could get pretty
nasty with all of the different mathematical rules. Does anyone have a
better idea than parsing to compute an equation from a string
representation?
Thanks so much!
