map() function works on each element of an iterable by applying the given function and returns the resultant list.
>>> map(int, ['1', '2', '3'])
[1, 2, 3]
In contrast the below implemented function would execute a chain of functions on a given argument.
function implementation:-
>>> fchain = lambda fnlist, argument: reduce( lambda x, fn: fn(x), [ argument ] + fnlist )
Example for running this:-
>>> def double(x):
... return x*2
...
>>> def triple(x):
... return x*3
>>> fchain([double, triple, double, double], 10)
240
