For instance, I've tried things like this, which doesn't work:
mydict = {
'funcList1': [foo(), bar(), goo()],
'funcList2': [foo(), goo(), bar()]}
Is there some kind of structure with this kind of functionality?
I realize that I could obviously do this just as easily with a bunch of def
statements:
def func1():
foo()
bar()
goo()
But the number of statements I need is getting pretty unwieldy and tough to remember. It would be nice to wrap them nicely in a dictionary that I could examine the keys of now and again.
Functions are first class objects in Python and so you can dispatch using a dictionary. For example, if foo
and bar
are functions, and dispatcher
is a dictionary like so.
dispatcher = {'foo': foo, 'bar': bar}
Note that the values are foo
and bar
which are the function objects, and NOT foo()
and bar()
.
To call foo
, you can just do dispatcher['foo']()
EDIT: If you want to run multiple functions stored in a list, you can possibly do something like this.
dispatcher = {'foobar': [foo, bar], 'bazcat': [baz, cat]}
def fire_all(func_list):
for f in func_list:
f()
fire_all(dispatcher['foobar'])
