I have the following lists
fncs = ["MyLinkedList","addAtHead","get","addAtTail"]
args = [[],[8],[1],[81]]
And I want to return
[MyLinkedList(), addAtHead(8), get(1), addAtTail(81)]
I thought I could use fnc_vals = [f(x) for f, x in zip(fncs, args)] but that doesn't seem to work since my fncs list is a list of strings. How can I apply a list of functions to a list of arguments (in Python)?
If you have a list of strings refering to the current scope functions you can use globals or locals:
fnc_vals = [golbals()[f](x) for f, x in zip(fncs, args)]
Check this example:
>>> def foo(x):
... return x
...
>>> globals()["foo"](10)
10
You can also build your own functions addressing dictionary:
>>> def foo(x):
... return x
...
>>> def bar(x):
... return x + 10
...
>>> func_dict = {f.__name__:f for f in (foo, bar)}
>>> func_dict["foo"](10)
10
If the functions are in the local namespace, just remove the quotes:
fncs = [MyLinkedList, addAtHead, get, addAtTail]
args = [[], [8], [1], [81]]
If the 1st list must be strings, you can get the function objects with:
function_names = ["MyLinkedList", "addAtHead", "get", "addAtTail"]
functions = [locals()[fn] for fn in function_names]
If, that is, the functions are named in the local namespace.
fncsbe a list of strings?
