I'm a 4th-year PhD student in evolutionary biology at Indiana University in
Bloomington, IN. I've been using Python for about a year for various
biology projects and am working on a package related to my dissertation
work. I am looking to replace Mathematica with SymPy in my workflow. I use
Git and Github for my research projects and for personal projects,
dotfiles, etc. as well.
Now for my question. Suppose I have an expression like the following:
from sympy import *
var('a:d')
w = Wild('w')
test = a * (1 - c) + b * (c - 1) + d
I'd like to rewrite test as (a - b) * (1 - c) + d
I tried test.replace(a * w - b * w, collect(a * w - b * w, w)), but this
does not work.
Many thanks in advance for your help.
