python - In sympy, is it possible for ratsimp to simplify also a non fraction element? -

with snippet:

from sympy import * init_printing(use_latex='mathjax') a,b,c=symbols('a b c') ratsimp(a+1/b+1/c) 

i get

a + (b + c)/(b*c) 

while

(a*b*c + b + c)/(b*c) 

because need numerator of fraction.

is possible?

as ratsimp documentation says, final step reduce rational function, extract polynomial part. since not want, should not use ratsimp. instead, use cancel on common denominator, , if want numerator , denominator separately, use .as_numer_denom()

>>> cancel(a+1/b+1/c) (a*b*c + b + c)/(b*c) >>> f, g = cancel(a+1/b+1/c).as_numer_denom() >>> f a*b*c + b + c >>> g b*c
