I've heard it said that Python is not a functional language, but if that were really the case, then functools would not exist. In addition to the example described above, I've had multiple occasions where having a general purpose function composition function would have simplified the implementation by providing a basic functional construct.
It's not like a basic variable-arity composition function is hard to implement though, it's basically:
def compose(*funcs): return reduce(lambda f1, f2: lambda v: f1(f2(v)), funcs)
it'll turn compose(a, b, c, d)(value) into a(b(c(d(value))))
