Given a string - execute a function by the same name

Arnaud,

Just when I thought my solution couldn't get any better :)

Thanks for that great tip and for an excellent demonstration of using a
decorator.

You could avoid #5 from the start using a decorator:

functions = {}

def register(func):
    functions[func.__name__] = func
    return func

@register
def foo(): print "Foo!"

@register
def bar(): print "Bar!"


>>> functions
{'foo': <function foo at 0x6f2f0>, 'bar': <function bar at 0x6f330>}
>>> functions['bar']()
Bar!
