Dear All,
I was hoping to use SymPy patterns to perform a transformation
equivalent to this Mathematica code:
f[a + 2*b + c] /. f[x_] -> g[x]
g[a + 2 b + c]
I.e. I wanted to replace calls to the (undefined) function f with calls
to the function g with the same arguments.
I tried the following, with f and g set up as undefined functions:
patt=Wild("p1")
f(a+2*b+c).subs(f(patt),g(patt))
f(a + 2*b + c)
Is there a way to do this?
David
