First, thanks for all your feedback.
I was playing around and came up with some alternative solutions:

def f1(str):
    return float(str)
def f2(str):
    return float(str) - 1 
def f3(str):
    return float(str)

str = ["2.144", "2.343", "3.14159"]
fn = [f1, f2, f3]

an alternative imperative approach:
z = []
for i in range(len(fn)):
    z.append(fn[i](str[i]))
print z

and a functional approach, which I like alot:
z = map(lambda f, arg: f(arg), fn, str)
print z


Cheers,
Brian
