Is there a way to evaluate a string in the "same way" as sage would
evaluate it? Or, to put it another way, maybe I'm just confused about
the way 'eval' works (or maybe eval isn't the right function) ...
sage: var('frac')
frac
sage: frac=eval('x/2')
sage: frac
x/2
But ...
sage: type(frac)
<class 'sage.calculus.calculus.SymbolicArithmetic'>
sage: frac=eval('1/2')
sage: frac
0
sage: type(frac)
<type 'int'>
Thanks,
-Mike
