Question

I want to apply a list of lambda functions to a single element using an iterable that has to be created with yield.

The list of lambda functions would have something like:

[<function <lambda> at 0x1d310c8>, <function <lambda> at 0x1d355f0>]

And I want to apply every function, from left to right , to a single element using yield to construct an iterable to iterate the list

Answer 1

def apply_all(functions, item):
    for f in functions:
        yield f(item)

Example usage:

functions = [type, id, hex]
for result in apply_all(functions, 55):
    print result

gives

<type 'int'>
