Is There A Way To Handle Constant Function Parameters In Sympy?
I am generating symbolic functions and using SymPy to simplify them. Now I would like a way to 'simplify' symbols that represent constant parameters in a function that is yet to b
Solution 1:
Perhaps something like this (applied to an expression that has been fully expanded):
defconsim(eq, *v):
con = numbered_symbols('c', cls=Dummy)
reps = {}
for i in preorder_traversal(eq):
if i.is_Mul or i.is_Add:
c, d = i.as_independent(*v)
if c != i.identity and c.free_symbols:
c = reps.setdefault(c, next(con))
return eq.subs(reps)
>>> from sympy.abc import a, b, c, d, x
>>> eq = 2*a*x**2 + b*c*x + d + e
>>> consim(eq, x)
2
c₀ + c₁⋅x + c₂⋅x
You probably want numbered symbols, not all symbols the same.
