the reason you get this error is because "2*3" is not a string
representation of an integer whereas "6" is. in other words 2*3 is not
a number.

Try eval("2*3")

If you have a string "6", and you do int("6"), you get the number 6.
But if you have a string "2*3" and you do int("2*3") you get a name error.
How do you take an expression in a string, and evaluate the expression
to get a number?
I want to be able to turn the string "2*3" into the number 6.
