It sounds like you're doing some data-directed programming. Out of
curiosity, would it be ok to store the function's name within your
tuple as well? For example:
def square(x): return x*x
def sqrt(x): return x**(.5)
functions = [("square", square), ## A dictionary may be a
("sqrt", sqrt)] ## better data structure
## for this.
for n, f in functions:
if n == name: return f
f_name = raw_input("Enter function name:")
f = getFunction(f_name)
if not f: break
This approach doesn't take too much advantage of many Python-specific
features. Hope this helps!
